Bright light! Bright light! @NASAJuno investigates what's powering #Jupiter's powerful and mysterious #aurora. This is a reconstructed view of Jupiter's northern lights through the filters of Juno's Ultraviolet Imaging Spectrometer (UVS) instrument on Dec. 11, 2016, as the Juno spacecraft approached Jupiter, passed over its poles, and plunged towards the equator. Such measurements present a real challenge for the spacecraft's science instruments: Juno flies over Jupiter's poles at 30 miles (50 kilometers) per second -- more than 100,000 miles per hour -- speeding past auroral forms in a matter of seconds.

The first, the last, the everything: #OTD in 1989, #Voyager 2 flew by #Neptune, returning the only close images ever of the big, blue world. This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach. The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called Scooter and the little dark spot are visible. These clouds were seen to persist for as long as Voyager's cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen. #space #science #planets #VGER #Voyager2 #Voyager40 #NASA #JPL | © instagram.com/nasajpl

Wavy Gravy: #Saturn’s cloud bands move at different speeds and directions depending on latitude. Turbulence where bands meet leads to wavy structure. Saturn’s upper atmosphere generates the faint haze seen along the limb (apparent edge) of the planet in this image. This false color view is centered on 46 degrees north latitude on Saturn. The images were taken with the Cassini spacecraft narrow-angle camera on May 18, 2017, using a combination of spectral filters which preferentially admit wavelengths of near-infrared light. The image filter centered at 727 nanometers was used for red in this image; the filter centered at 750 nanometers was used for blue. (The green color channel was simulated using an average of the two filters.) #space #science #planet #clouds #Cassini #JPL #NASA #ESA | © instagram.com/nasajpl

This week, @NASA's #Cassini spacecraft will begin its final five orbits around #Saturn. The spacecraft will enter new territory in its final mission phase, the #Grand Finale, as it prepares to embark on a set of ultra-close passes through the planet’s upper atmosphere.  Cassini will make the first of these five passes over Saturn at 9:22 p.m. PDT Sunday, Aug. 13 (12:22 a.m. EDT Monday, Aug. 14). The spacecraft's point of closest approach to Saturn during these passes will be between about 1,010 and 1,060 miles (1,630 and 1,710 kilometers) above Saturn's cloud tops.  The spacecraft is expected to encounter atmosphere dense enough to require the use of its small rocket thrusters to maintain stability -- conditions similar to those encountered during many of Cassini's close flybys of Saturn's moon #Titan, which has its own dense atmosphere.

The #Cassini mission is using the unparalleled opportunity to observe changes that occur on the planet as the Saturnian seasons turn. This view looks toward the sunlit side of the rings from about 17 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on April 17, 2017 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 939 nanometers. The view was acquired at a distance of approximately 733,000 miles (1.2 million kilometers) from Saturn.

Need to get away? Take a mini vacation and soar over dwarf planet #Ceres with @NASA's #Dawn mission. Occator Crater on Ceres is home to the brightest area on the entire dwarf planet. At 57 miles (92 kilometers) wide and 2.5 miles (4 kilometers) deep, Occator displays evidence of recent geologic activity. NASA's Dawn mission found that the bright spots may have been produced by upwelling of salt-rich liquids after the impact that formed the crater. Pan and zoom as you fly over the crater with Dawn in this 360-degree animation made with observations from the spacecraft.

NASA’s #Cassini mission to #Saturn is sending back some weird science from its final mission phase, the #GrandFinale. So what’s up? The planet’s magnetic field has no discernable tilt, which is strange, and also makes it difficult to figure out how long a day on Saturn really is. Cassini got its first-ever samples of the planet's atmosphere and main rings, and saw mysterious plateaus in the rings. Find out more at https://go.nasa.gov/2utei1a (link in bio). This view from the spacecraft gazes toward the rings beyond Saturn's sunlit horizon. Along the limb (the planet's edge) at left can be seen a thin, detached haze. This haze vanishes toward the left side of the scene. This view is a composite made using images taken in red, green and ultraviolet spectral filters. The images were obtained using the Cassini spacecraft narrow-angle camera on July 16, 2017, at a distance of about 777,000 miles (1.25 million kilometers) from Saturn. Image scale is about 4 miles (7 kilometers) per pixel on Saturn. #space #science #planet #ESA #NASA #JPL | © instagram.com/nasajpl

Are you ready for #eclipse2017? Solar eclipses occur when the new moon passes between Earth and the sun and the moon casts a traveling shadow on Earth. A total solar eclipse occurs when the new moon is in the right position to exactly cover the sun's disk. This will happen on Aug. 21, 2017, when the new moon will completely block our view of the sun along a narrow path from Oregon to South Carolina. During August's total solar eclipse it may be dark enough to see some of the brighter stars and a few planets! Two weeks before or after a solar eclipse there's often, but not always, a lunar eclipse. But it's not necessarily a total lunar eclipse. This will happen because the moon will be at opposition. The full moon and Earth and the sun will be lined up with Earth in the middle. #space #science #sun #moon #eclipse #NASA #JPL | © instagram.com/nasajpl

The sharp eye of @NASA's #Hubble Space Telescope has captured the tiny moon #Phobos during its orbital trek around #Mars. Because the moon is so small, it appears star-like in the Hubble pictures. Over the course of 22 minutes, Hubble took 13 separate exposures, allowing astronomers to create a time-lapse video showing the diminutive moon's orbital path. The Hubble observations were intended to photograph Mars, and the moon's cameo appearance was a bonus. A football-shaped object just 16.5 miles by 13.5 miles by 11 miles, Phobos is one of the smallest moons in the solar system. It is so tiny that it would fit comfortably inside the Washington, D.C.

Nearly five years after its celebrated arrival at #Mars, the #Curiosity rover continues to reveal Mars as a once-habitable planet. Early in the planet’s history, generations of streams and lakes created the landforms that Curiosity explores today. The rover currently is climbing through the foothills of Mount Sharp, a 3-mile-high mountain formed from sediment brought in by water and wind. This talk covers the latest findings from the mission, the challenges of exploration with an aging robot, and what lies ahead.

Ruffles have ridges, and so does #Mars. @NASA’s #Curiosity rover is now studying the iron-bearing "Vera Rubin Ridge," which stretches about 4 miles (6.5 kilometers), end-to-end, on the northwestern flank of lower Mount Sharp. The mission’s science team nicknamed the feature to commemorate astronomer Vera Cooper Rubin (1928-2016). Vera Rubin Ridge stands about eight stories tall, with a trough behind it where clay minerals await. Curiosity is now near the downhill face. The scale bars indicate dimensions, in meters, at two distances from the rover. The nearer scale bar refers to features about 2,000 feet (610 meters) from the camera, near the base of the ridge. The farther scale bar refers to features about 2,300 feet (700 meters) from the camera, at the top of the ridge. A major appeal of the ridge is an iron-oxide mineral, hematite, which can form under wet conditions and reveal information about ancient environments on Mars. Hematite-bearing rocks elsewhere on the Red Planet were the scientific basis for choosing the 2004 landing site of an older and still-active rover, Opportunity. #Mars #space #science #rover #NASA #JPL #exploration #discovery #geology #rocks | © instagram.com/nasajpl

It’s a new dawn: The light of a new day on #Saturn illuminates the planet’s wavy cloud patterns and the smooth arcs of the vast rings. The light has traveled around 80 minutes since it left the sun's surface by the time it reaches Saturn. The illumination it provides is feeble; Earth gets 100 times the intensity since it's roughly ten times closer to the sun. Yet compared to the deep blackness of space, everything at Saturn still shines bright in the sunlight, be it direct or reflected. This view looks toward the sunlit side of the rings from about 10 degrees above the ring plane. The image was taken with the #Cassini spacecraft wide-angle camera on Feb. 25, 2017 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 939 nanometers. The view was obtained at a distance of approximately 762,000 miles (1.23 million kilometers) from Saturn.

Careful driver: a new algorithm on @NASA’s #Curiosity rover reduces wear on the rover’s wheels. The software, referred to as traction control, adjusts the speed of Curiosity's wheels depending on the rocks it's climbing. After 18 months of testing at NASA's Jet Propulsion Laboratory in Pasadena, California, the software was uploaded to the rover in March. Mars Science Laboratory's mission management approved it for use on June 8, after extensive testing at JPL and multiple tests on Mars.

All shapes and sizes: This montage of views from @NASA’s #Cassini mission shows three of #Saturn’s small moons: Atlas, Daphnis and Pan. Two differences between Atlas and Pan are obvious in this montage. Pan's equatorial band is much thinner and more sharply defined, and the central mass of Atlas (the part underneath the smooth equatorial band) appears to be smaller than that of Pan. All of these images were taken using the Cassini spacecraft narrow-angle camera. The images of Atlas were acquired on April 12, 2017, at a distance of 10,000 miles (16,000 kilometers) and at a sun-moon-spacecraft angle (or phase angle) of 37 degrees. The images of Pan were taken on March 7, 2017, at a distance of 16,000 miles (26,000 kilometers) and a phase angle of 21 degrees. The Daphnis image was obtained on Jan. 16, 2017, at a distance of 17,000 miles (28,000 kilometers) and at a phase angle of 71 degrees. All images are oriented so that north is up. #moons #shapes #sizes #solarsystem #NASA #JPL | © instagram.com/nasajpl

Red Planet Whodunit: Opportunity is searching for clues as to whether wind or water carved this Martian channel. Investigate more: https://go.nasa.gov/2t3GRDS (link in bio). The location is just outside the crest line of the western rim of Mars’ Endeavour Crater, looking toward the northwest. A swath across the top half of the image is lined with dark rocks, and one possible history under investigation is that it was a channel into a lake perched against the edge of the crater billions of years ago. Another hypothesis is that the linear pattern of rock piles is related to fractures from the impact that excavated Endeavour Crater. For scale, the width of the swath near the center of the image is roughly 30 feet (9 meters). Opportunity's panoramic camera (Pancam) recorded this scene on June 3, 2017, during the 4,749th Martian day, or sol, of the rover's work on Mars. The enhanced color helps make differences in surface materials visible.

Gotcha! Mars Reconnaissance Orbiter captures @NASA’s #Curiosity rover in action, climbing Mount Sharp—seen here as a blue dot. Using the most powerful telescope ever sent to Mars, NASA's Mars Reconnaissance Orbiter caught a view of the Curiosity rover this month amid rocky mountainside terrain. The car-size rover, climbing up lower Mount Sharp toward its next destination, appears as a blue dab against a background of tan rocks and dark sand in the enhanced-color image from the orbiter's High Resolution Imaging Science Experiment (HiRISE) camera. The exaggerated color, showing differences in Mars surface materials, makes Curiosity appear bluer than it really looks. The image was taken on June 5, 2017, two months before the fifth anniversary of Curiosity's landing near Mount Sharp on Aug. 5 PDT (Aug. 6, 2017, EDT and Universal Time).

News from beyond our solar system: @NASA's #Kepler's team has released a mission catalog of planet candidates that introduces 219 new candidates, 10 of which are near-Earth size and orbiting in their star's habitable zone, which is the range of distance from a star where liquid water could pool on the surface of a rocky planet. This is the most comprehensive and detailed catalog release of candidate exoplanets, which are planets outside our solar system, from Kepler's first four years of data. It's also the final catalog from the spacecraft's view of the patch of sky in the Cygnus constellation. With the release of this catalog, derived from data publicly available on the NASA Exoplanet Archive, there are now 4,034 planet candidates identified by Kepler. Of those, 2,335 have been verified as exoplanets. Of roughly 50 near-Earth size habitable zone candidates detected by Kepler, more than 30 have been verified.

This view from @NASA’s #Cassini mission shows two different effect of moons that cause waves in Saturn's A ring and kinks in its F ring. The A ring, which takes up most of the image on the left side, displays waves caused by orbital resonances with moons that orbit beyond the rings. Kinks, clumps and other structures in the F ring (the small, narrow ring at right) can be caused by interactions between the ring particles and the moon Prometheus, which orbits just interior to the ring, as well as collisions between small objects within the ring itself. This view looks toward the sunlit side of the rings from about 22 degrees above the ring plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 22, 2017. The view was acquired at a distance of approximately 63,000 miles (101,000 kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 7 degrees. Image scale is 1,979 feet (603 meters) per pixel. #photography #blackandwhite #Saturn #space #solarsystem #NASA #JPL | © instagram.com/nasajpl

Saturn tonight is big and bright ??? it's at opposition! This video shows when and where to look. #Saturn reaches opposition on June 15 when Saturn, Earth and the Sun are all in a straight line with Earth in the middle. Opposition provides the best and closest views of Saturn and several of its brightest moons. Through a telescope you'll be able to see Saturn's rings tilted toward Earth about as wide as they get: 26.6 degrees. Sunlight reflecting off ring particles makes the rings look even brighter. #fun #astronomy #nightsky #space #planet #whatsup #NASA #JPL | © instagram.com/nasajpl

One Summer Dream: @NASA’s #Cassini mission sees bright methane clouds drifting in the dog day skies of #Saturn’s moon #Titan, along with dark hydrocarbon lakes and seas clustered around the north pole. Compared to earlier in Cassini's mission, most of the surface in the moon's northern high latitudes is now illuminated by the sun. Summer solstice in the Saturn system occurred on May 24, 2017. The image was taken with the Cassini spacecraft narrow-angle camera on June 9, 2017, using a spectral filter that preferentially admits wavelengths of near-infrared light centered at 938 nanometers. Cassini obtained the view at a distance of about 315,000 miles (507,000 kilometers) from Titan. #blackandwhite #photography #moon #solarsystem #NASA #JPL | © instagram.com/nasajpl

This view from the @NASA #Dawn mission shows the diverse and complex geology on dwarf planet #Ceres, which can help scientists reconstruct its history. It shows familiar features: Occator Crater with its bright deposits (called faculae) of carbonates and other salts, a series of linear features (at right) called Samhain Catenae, and another large crater on the right side of the image called Kirnis. A relatively fresh crater called Lociyo, superimposed on an older crater, can be seen toward the bottom left of the picture. Occator appears to be one of the youngest features in this picture, except for a couple of smaller craters. The 71-mile-wide (115-kilometer-wide) Kirnis Crater on the other hand is an old, eroded crater. It owes its peculiar polygonal shape in part to its overlap with one of the Samhain Catenae. This illustrates the role of fractures in driving the geometry of some of Ceres' craters. Kirnis Crater is named after a Lithuanian spirit-guardian of cherry trees, whereas the Samhain Catenae refer to a Gaelic festival organized at the end of the harvest season. It was observed in Ireland and Scotland during seven days in October and November, nearly halfway between the autumn equinox and the winter solstice. This picture was obtained on June 25, 2015, from an altitude of 2,700 miles (4,400 kilometers). It is centered at 1.7 degrees north latitude, and 249 degrees east longitude. #science #dwarfplanet #space #brightspots #NASA #JPL | © instagram.com/nasajpl

#Saturn's moon Iapetus is a world of contrast, with light and dark regions fitting together like cosmic puzzle pieces.  Cassini Regio on Iapetus (914 miles or 1,471 kilometers across) is covered in a layer of dark, dusty material creating a stark contrast to the much brighter region that surrounds it. This leads to the moon's distinctive, two-toned appearance. This view looks toward Saturn-facing hemisphere of Iapetus. North on Iapetus is up and rotated 20 degrees to the right.

Red dwarf stars erupt with intense flares and may threaten planet habitability.  Cool dwarf stars are hot targets for exoplanet hunting right now. The discoveries of planets in the habitable zones of the #TRAPPIST1 and LHS 1140 systems, for example, suggest that Earth-sized worlds might circle billions of red dwarf stars, the most common type of star in our galaxy. Are red dwarfs really as friendly to life as they appear, or do these flares make the surfaces of any orbiting planets inhospitable?

A newly discovered Jupiter-like world is so hot, it's being vaporized by its own star.  With a dayside temperature of more than 7,800 degrees Fahrenheit (4,600 Kelvin), KELT-9b is a planet that is hotter than most stars. But its blue A-type star, called KELT-9, is even hotter -- in fact, it is probably unraveling the planet through evaporation. KELT-9b is 2.8 times more massive than Jupiter, but only half as dense. Scientists would expect the planet to have a smaller radius, but the extreme radiation from its host star has caused the planet's atmosphere to puff up like a balloon.

It is large enough for its own gravity to have made it round, but isn't one of the really large moons in our solar system, like Titan. Even enormous Titan is tiny beside the mighty gas giant Saturn. This view looks toward Saturn from the sunlit side of the rings, from about 27 degrees above the ring plane.

Collapse pit or an impact crater? New orbital images from @UAHiRISE say it can't be both. This observation from NASA's Mars Reconnaissance Orbiter show it is late summer in #Mars’ Southern hemisphere, so the sun is low in the sky and subtle topography is accentuated in orbital images.  We see many shallow pits in the bright residual cap of carbon dioxide ice (also called "Swiss cheese terrain"). There is also a deeper, circular formation that penetrates through the ice and dust. This might be an impact crater or it could be a collapse pit. Credit: @NASA/@NASAJPL-@CaltechEdu/@UArizona #science #space #NASA #JPL | © instagram.com/nasajpl

Thwaites Glacier is melting rapidly, but not as fast as earlier research predicted.  The melt rate of West Antarctica's Thwaites Glacier is an important concern, because this glacier alone is currently responsible for about 1 percent of global sea level rise.  The new study, published in the journal Geophysical Research Letters, finds that numerical models used in previous studies have overestimated how rapidly ocean water is able to melt the glacier from below, leading them to overestimate the glacier's total ice loss over the next 50 years by about 7 percent.

Before @Cassini entered its Grande Finale orbits, it acquired unprecedented views of the outer edges of the main ring system.  For example, this close-up view of the Keeler Gap, which is near the outer edge of Saturn's main rings, shows in great detail just how much the moon Daphnis affects the edges of the gap. This view looks toward the sunlit side of the rings from about 3 degrees above the ring plane. The view was acquired at a distance of approximately 18,000 miles (30,000 kilometers) from Daphnis and at a Sun-Daphnis-spacecraft, or phase, angle of 69 degrees. Image scale is 581 feet (177 meters) per pixel.

Saturn Solstice Salutations! ?Summer starts today in the planet's northern hemisphere, home to the polar hexagon, seen here by @NASA’s #Cassini mission. This natural color view from April 2017 shows most of the hexagon's interior was covered in yellowish haze, and only the center of the polar vortex retained the blue color observed years before. Seasonal arrival of the sun's ultraviolet light triggers the formation of photochemical aerosols, leading to haze formation. The general yellowing of the polar region is believed to be caused by smog particles produced by increasing solar radiation shining on the polar region as Saturn approached the northern summer solstice on May 24, 2017.

Scientists using @NASA's #Kepler space telescope identified a regular pattern in the orbits of the planets in the #TRAPPIST1 system that confirmed suspected details about the orbit of its outermost and least understood planet, TRAPPIST-1h. TRAPPIST-1 is only eight percent the mass of our sun, making it a cooler and less luminous star. It's home to seven Earth-size planets, three of which orbit in their star's habitable zone -- the range of distances from a star where liquid water could pool on the surface of a rocky planet. The system is located about 40 light-years away in the constellation of Aquarius. The star is estimated to be between 3 billion and 8 billion years old.

You Spin Me Round: @NASA’s #Dawn mission successfully observed #Ceres at opposition, taking images from a position exactly between the sun and Ceres’ surface. Mission specialists had carefully maneuvered Dawn into a special orbit so that the spacecraft could view Occator Crater, which contains the brightest area of Ceres, from this new perspective. This movie shows the opposition images, with contrast enhanced to highlight brightness differences. The bright spots of Occator stand out particularly well on an otherwise relatively bland surface.

Little Shadow: #Saturn’s shadow on the rings grows shorter as the planet’s season advances toward northern summer, thanks to the planet's permanent tilt as it orbits the sun. This will continue until Saturn's solstice in May 2017. At that point in time, the shadow will extend only as far as the innermost A ring, leaving the middle and outer A ring completely free of the planet's shadow. Over the course of the Cassini mission, the shadow of Saturn first lengthened steadily until equinox in August 2009. Since then, the shadow has been shrinking. This view looks toward the sunlit side of the rings from about 10 degrees above the ring plane. The image was taken in visible light with @NASA’s #Cassini spacecraft's wide-angle camera on Feb. 3, 2017. The view was acquired at a distance of approximately 760,000 miles (1.2 million kilometers) from Saturn.

Work ? @NASA’s #Opportunity #rover reached the main destination of her two-year extended mission and begins the study of #ancient "Perseverance Valley." As the rover approached the upper end of Perseverance Valley in early May, images from its cameras began showing parts of the area in greater resolution than what can be seen in images taken from orbit above Mars. The process that carved Perseverance Valley into the rim of Endeavour Crater billions of years ago has not yet been identified. Among the possibilities: It might have been flowing water, or might have been a debris flow in which a small amount of water lubricated a turbulent mix of mud and boulders, or might have been an even drier process, such as wind erosion. The mission's main objective with Opportunity at this site is to assess which possibility is best supported by the evidence still in place.

The #Cassini mission’s findings have revolutionized our understanding of #Saturn, its complex rings, the amazing assortment of moons and the planet’s dynamic magnetic environment. Icy jets shoot from the tiny moon #Enceladus; #Titan’s hydrocarbon lakes and seas are dominated by liquid ethane and methane, and complex pre-biotic chemicals form in the atmosphere and rain to the surface. What new puzzles will Cassini solve before it plunges into Saturn’s atmosphere, rather than risk crashing into one of Saturn’s ocean worlds and contaminating it? Hear the story of recent science discoveries and the upcoming excitement during Cassini’s final orbits. Dr. Linda Spilker, Cassini Project Scientist, presents highlights of Cassini’s ambitious inquiry at Saturn and an overview of science observations in the final orbits. Dr. Earl Maize, Cassini Program Manager, discusses Cassini’s exciting challenges, ultimately flying through a region where no spacecraft has ever flown before.

Cracking the Crab Nebula ? Astronomers have produced a highly detailed image of the Crab Nebula, by combining data from telescopes spanning nearly the entire breadth of the electromagnetic spectrum, from radio waves seen by the Karl G. Jansky Very Large Array (VLA) to the powerful X-ray glow as seen by the orbiting Chandra X-ray Observatory. And, in between that range of wavelengths, the Hubble Space Telescope's crisp visible-light view, and the infrared perspective of the Spitzer Space Telescope.The Crab Nebula, the result of a bright supernova explosion seen by Chinese and other astronomers in the year 1054, is 6,500 light-years from Earth. At its center is a super-dense neutron star, rotating once every 33 milliseconds, shooting out rotating lighthouse-like beams of radio waves and light -- a pulsar (the bright dot at image center). The nebula's intricate shape is caused by a complex interplay of the pulsar, a fast-moving wind of particles coming from the pulsar, and material originally ejected by the supernova explosion and by the star itself before the explosion. This image combines data from five different telescopes: the VLA (radio) in red; Spitzer Space Telescope (infrared) in yellow; Hubble Space Telescope (visible) in green; XMM-Newton (ultraviolet) in blue; and Chandra X-ray Observatory (X-ray) in purple. #space #astronomy #exploration #crabnebula #nebula #NASA #JPL | © instagram.com/nasajpl

That feathered look: @NASA’s #Cassini mission captured this view of bands of bright methane clouds drifting across #Saturn’s moon #Titan. The view was obtained during a distant (non-targeted) flyby, during which Cassini passed 303,000 miles (488,000 kilometers) above the moon's surface. Although Cassini will have no further close, targeted flybys of Titan, the spacecraft continues to observe the giant moon and its atmosphere from a distance. The dark regions at top are Titan's hydrocarbon lakes and seas. The image was taken on May 7, 2017, at a distance of 316,000 miles (508,000 kilometers). The view is an orthographic projection centered on 57 degrees north latitude, 48 degrees west longitude. An orthographic view is most like the view seen by a distant observer.

The hexagonal polar jet stream is the shining feature of almost every view of the north polar region of #Saturn. The region, in shadow for the first part of the Cassini mission, now enjoys full sunlight, which enables Cassini scientists to directly image it in reflected light. Although the sunlight falling on the north pole of Saturn is enough to allow us to image and study the region, it does not provide much warmth. In addition to being low in the sky (just like summer at Earth's poles), the sun is nearly ten times as distant from Saturn as from Earth. This results in the sunlight being only about 1 percent as intense as at our planet. Photo by @NASA’s #Cassini mission. #planet #solarsystem #space #hexagon #NASA #JPL | © instagram.com/nasajpl

Got a minute? This 60-second video explains why a year on #Mars is almost twice as long as a year on #Earth. On May 5, 2017, Mars passes solar longitude 0 as the Sun crosses the equator on Mars. This is the vernal equinox, and was chosen by planetary scientists as the start of a ?new year ? (A Mars year is 687 Earth days). For any planet, a year is the time it takes to make one orbit around the sun. It takes Mars about twice as long as it does for Earth to make one circle around the sun. Therefore, a year on Mars lasts twice as long.

In the north, #Enceladus' surface appears to be about as old as any in the solar system. The south, however, is an entirely different story. The north polar area of Enceladus (313 miles or 504 kilometers across) seen here is heavily cratered, an indication  that the surface has not been renewed since quite long ago. But the south polar region shows signs of intense geologic activity, most prominently focused around the long fractures known as "tiger stripes" that spray gas and tiny particles from the moon. This view looks toward the leading side of Enceladus. North on Enceladus is up and rotated 38 degrees to the left. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 27, 2016. #Cassini #moon #surface #solarsystem #NASA #JPL | © instagram.com/nasajpl

The Sounds of Silence are the Sounds of Science... yet to come. @NASA's #Cassini mission to #Saturn found such little dust in the gap between the planet and its rings that the team is confident about a clear path for remaining orbits of the mission's #GrandFinale. This video was made using data the Radio and Plasma Wave Science, or RPWS, instrument collected as Cassini made the first dive ever through the gap between Saturn and its rings on April 26, 2017. Very few pops and cracks are audible at all. A dustier environment in the gap might have meant the spacecraft's saucer-shaped main antenna would be needed as a shield during most future dives through the ring plane. This would have forced changes to how and when Cassini's instruments would be able to make observations. Fortunately, it appears that the "plan B" option is no longer needed. (There are 21 dives remaining. Four of them pass through the innermost fringes of Saturn's rings, necessitating that the antenna be used as a shield on those orbits.)

The low angle of the sun over moon Tethys' massive canyon, Ithaca Chasma, highlights the contours of the rift in this photo by @NASA’s #Cassini mission. Ithaca Chasma is up to 60 miles (100 kilometers) wide, and runs nearly three-fourths of the way around icy Tethys (660 miles or 1,062 kilometers across). The canyon has a maximum depth of nearly 2.4 miles (4 kilometers) deep. The giant crater Odysseus -- usually one of Tethys’ most recognizable features-- is barely seen in profile along the limb, at upper left. This view looks toward the Saturn-facing hemisphere of Tethys. North on Tethys is up and rotated 5 degrees to the left. The image was taken in green light with the Cassini spacecraft narrow-angle camera on Jan. 30, 2017. The view was obtained at a distance of approximately 221,000 miles (356,000 kilometers) from Tethys. Image scale is 1 mile (2 kilometers) per pixel. #rift #space #moon #solarsystem #Saturn #NASA #JPL #NASAbeyond | © instagram.com/nasajpl

Our home ? @NASA’s #Cassini mission celebrates #EarthDay early by imaging our #Earth and moon nestled between the rings of #Saturn. Zoom in to get a good look at the moon to the left of Earth. The spacecraft captured the view on April 12, 2017 at 10:41 p.m. PDT (1:41 a.m. EDT). Cassini was 870 million miles (1.4 billion kilometers) away from Earth when the image was taken. Although far too small to be visible in the image, the part of Earth facing toward Cassini at the time was the southern Atlantic Ocean. The rings visible here are the A ring (at top) with the Keeler and Encke gaps visible, and the F ring (at bottom). During this observation Cassini was looking toward the backlit rings, making a mosaic of multiple images, with the sun blocked by the disk of Saturn. Seen from Saturn, Earth and the other inner solar system planets are all close to the sun, and are easily captured in such images, although these opportunities have been somewhat rare during the mission. The F ring appears especially bright in this viewing geometry. #home #planet #solarsystem #space #travel #exploration #science #NASA #JPL | © instagram.com/nasajpl

Slip Slidin' Away: @NASA's Dawn spacecraft has revealed many landslides on Ceres, which seem to have been shaped by a significant amount of water ice. The team identified three types of landslides. Type I, which are relatively round and large, have thick "toes" at their ends. They look similar to rock glaciers and icy landslides on Earth. Type II look similar to deposits left by avalanches on Earth. Type III features appear to involve melted ice, although scientists do not know if they actually contain liquid water. These landslides seem to be related to impact craters, and may have formed when an impacting body heats ice on Ceres. The resemble fluid material ejected from craters in the icy regions of Mars and Jupiter's moon Ganymede. #science #space #solarsystem #NASA #JPL #NASABeyond @GeorgiaTech | © instagram.com/nasajpl

Southbound & Down: Now more than 13 years into a mission slated to run for three month, @NASA's Opportunity Mars rover is departing "Cape Tribulation" (pictured here) for "Perseverance Valley." The rover will look for clues to what carved the valley billions of years ago: water, wind or flowing debris? If it was a debris flow initiated by a little water, it should be a jumbled mess. If it was a river cutting a channel, we may see gravel bars, crossbedding, or a pattern of sediments with the coarsest rocks at the bottom. Another pattern that could be evidence of flowing water would be if long pieces of gravel stacked and leaning in the same direction, which would show a past downstream flow. #Mars #science #engineering #space #Martian #water #geology #discovery #exploration #NASA #JPL | © instagram.com/nasajpl

Astrodynamics ain’t easy, but it’s necessary. See the #CrazyEngineering that will swing @NASA’s #Cassini mission around #Titan and into the gap between #Saturn & its rings. Cassini will make its final close flyby of Titan this weekend. The flyby marks the mission's final opportunity for up-close observations of the lakes and seas of liquid hydrocarbons that spread across the moon's northern polar region, and the last chance to use its powerful radar to pierce the haze and make detailed images of the surface.

Space pants? Not quite, but 3-D printed metallic "space fabric" does link fashion and engineering. Developed by the engineer son of a Spanish fashion designer, these prototypes look like chain mail, with small silver squares strung together. But these fabrics were not sewn by hand; instead, they were "printed," created in one piece with advanced technologies. These fabrics could potentially be useful for large antennas and other deployable devices, because the material is foldable and its shape can change quickly. The fabrics could also eventually be used to shield a spacecraft from meteorites, for astronaut spacesuits, or for capturing objects on the surface of another planet. One potential use might be for an icy moon like Jupiter's Europa, where these fabrics could insulate the spacecraft. At the same time, this flexible material could fold over uneven terrain, creating "feet" that won't melt the ice under them.

When imaged at infrared wavelengths that pierce the planet’s upper haze layer, the high-speed winds of #Saturn's atmosphere produce watercolor-like patterns. With no solid surface creating atmospheric drag, winds on Saturn can reach speeds of more than 1,100 miles per hour (1,800 kilometers per hour) -- some of the fastest in the solar system. This view was taken from a vantage point about 28 degrees above Saturn's equator. The image was taken with the Cassini spacecraft wide-angle camera on Dec. 2, 2016, with a combination of spectral filters which preferentially admits wavelengths of near-infrared light centered at 728 nanometers. The view was acquired at a distance of approximately 592,000 miles (953,000 kilometers) from Saturn. Image scale is 35 miles (57 kilometers) per pixel. #Cassini #painterly #blackandwhite #space #exploration #NASA #ESA #JPL #NASABeyond | © instagram.com/nasajpl

Dim sum? And then some! @NASA's #Cassini mission just returned the best-ever views of #Saturn’s tiny dumpling-shaped moon, #Atlas. These raw, unprocessed images were taken on April 12, 2017, at a close-approach distance of about 7,000 miles (11,000 kilometers). Atlas (about 19 miles, or 30 kilometers across) orbits Saturn just outside the A ring -- the outermost of the planet's bright, main rings.

Make it so: @NASA’s Deep Space Network relays one of the command sequences to begin Cassini's #GrandFinale. Throughout #Cassini's nearly 20-year mission, the flight team on Earth has transmitted between four and 10 weeks of commands to the spacecraft at a time. This transmission on April 11, 2017, was special. The team sent one of the final command sequences, which will control Cassini while it flies toward and eventually through the gap between Saturn's innermost ring and the planet itself. It takes nearly an hour and a half of light-travel time from Earth for the commands to reach the spacecraft at Saturn. Cassini will now autonomously execute that Grand Finale sequence for the next six weeks. Another command sequence will continue the Grand Finale orbits, which last for five months. ?☝️ #spacecraft #solarsystem #Saturn #Earth #NASA #JPL @nasasolarsystem | © instagram.com/nasajpl

This is a solar eruption from Sept. 26, 2014, seen by @NASA's Solar Dynamics Observatory. If erupted solar material reaches Earth, it can deplete the electrons in the upper atmosphere in some locations while adding electrons in others, disrupting communications either way. Better understanding how these storms interact with our upper atmosphere can help with radio communication and navigation.

Saturn's C ring isn't uniformly bright. Instead, about a dozen regions of the ring stand out as noticeably brighter than the rest of the ring, while about half a dozen regions are devoid of ring material. Scientists call the bright regions "plateaus" and the devoid regions "gaps.” Scientists have determined that the plateaus are relatively bright because they have higher particle density and reflect more light, but researchers haven't solved the trickier puzzle of how the plateaus are created and maintained. #Cassini #Saturn #spacecraft #solarsystem #NASA #ESA #JPL #space #science | © instagram.com/nasajpl

Dwarf planet #Ceres may have a very weak, temporary atmosphere, but mysteries linger about how it came to be and why it’s not always there. Now, researchers from @NASA's #Dawn mission suggest that this temporary atmosphere is related to the behavior of the sun. Energetic particles from the sun hitting exposed ice and ice near the surface transfer energy to the water molecules as they collide. This frees the water molecules from the ground, allowing them to escape and create a tenuous atmosphere that may last for a week or so. This animation shows data Dawn gathered about the hydrogen content of the upper yard, or meter, of Ceres' surface, represented here by blue (higher content) and red (lower content). Some of this hydrogen is in the form of ice, related to a possible tenuous atmosphere around the dwarf planet.

The propeller "Earhart" -- a disturbance in #Saturn’s ring caused by a small moonlet-- is seen in a new view from @NASA's #Cassini mission at a much higher resolution than ever before. Propellers are disturbances in the ring caused by a central moonlet. The moonlet itself would be a few pixels wide in this view, but it is difficult to distinguish from (and may be obscured by) the disturbed ring material that surrounds it.

Filling in the blanks: The #Mars Reconnaissance Orbiter has completed 50,000 orbits, revealing details about 99.1 percent of the planet. No other camera ever sent to Mars has photographed so much of the planet in such high resolution. MRO's Context Camera (CTX) exploits a sweet spot in the balance between resolution and image file size. With a resolution of about 20 feet (6 meters) per pixel in images of the Martian surface. The Context Camera has taken about 90,000 images since the spacecraft began examining Mars from orbit in late 2006. Each one reveals shapes of features down to sizes smaller than a tennis court, in a swath of ground about 18.6 miles (30 kilometers) wide. In addition to observing nearly the entire planet at least once, the Context Camera has observed 60.4 percent of the planet more than once. These observations aid science directly and also certify the safety of future landing sites.
