List nasa's Instagram Phobos photobombs Hubble’s look at Mars! When the Hubble Space Telescope observed Mars near opposition in May 2016, a sneaky companion photobombed the picture. Phobos, the Greek personification of fear, is one of two tiny moons orbiting Mars. In 13 exposures over 22 minutes, Hubble captured a timelapse of Phobos moving through its 7-hour 39-minute orbit.

This timelapse video captures a portion of the path that tiny Phobos takes around Mars. The transitions between frames have been smoothed to illustrate continuous motion. Phobos completes an orbit in just 7 hours and 39 minutes, which is faster than Mars rotates. Rising in the Martian west, it runs three laps around the Red Planet in the course of one Martian day, which is about 24 hours and 40 minutes. It is the only natural satellite in the solar system that circles its planet in a time shorter than the parent planet’s day. Hubble photographed Phobos orbiting the Red Planet on May 12, 2016, when Mars was 50 million miles from Earth. This was just a few days before the planet passed closer to Earth in its orbit than it had in the past 11 years.

List nasa's Instagram Tucked away in a small constellation around 30 million light-years from us is this relatively dim, low-star-forming galaxy. While it is not all that remarkable, it is still a beautiful and ethereal sight.

At this distance from Earth, actually not all that far on a cosmic scale, this galaxy is visible to anyone armed with even a basic telescope, as British astronomer William Herschel found when he discovered it in 1788.

This image shows the galaxy’s bright center and the surrounding dimmer and more diffuse “fuzz.” Despite appearing to be relatively bright in this image, studies have found that this galaxy is actually dim.

List nasa's Instagram How do eclipses work? 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 next month 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.

List nasa's Instagram On this day in 1969, NASA astronauts Neil Armstrong and Buzz Aldrin took “one small step” and planted the first human feet on another world, our moon. At 10:56 p.m. EDT, with more than half a billion people watching on television, Armstrong climbs down the ladder and proclaims: “That’s one small step for a man, one giant leap for mankind.” Aldrin joins him shortly, and offers a simple but powerful description of the lunar surface: “magnificent desolation.” They leave behind an American flag, a patch honoring the fallen Apollo 1 crew and a plaque on one of Eagle’s legs. It reads, “Here men from the planet Earth first set foot upon the moon. July 1969 A.D. We came in peace for all mankind.” Armstrong and Aldrin blast off and dock with Michael Collins in the Columbia Command Module.

List nasa's Instagram Freaky fast and really awesome! NASA astronaut Jack Fischer posted this GIF to his social media Tuesday saying, “I was checking the view out the back window & decided to take a pic so you can see proof of our ludicrous speed! #SpaceIsAwesome”. In case you didn’t know, the International Space Station travels 17,500 miles per hour as it orbits 250 miles above the Earth. 
Currently, three humans are living and working there, conducting important science and research. The orbiting laboratory is home to more than 250 experiments, including some that are helping us determine the effects of microgravity on the human body. Research on the station will not only help us send humans deeper into space than ever before, including to destinations like Mars, but also benefits life here on Earth.

List nasa's Instagram What appears to be a floating orb in the blackness of space is actually Saturn’s icy moon Enceladus. Here, intriguing south-polar jets are visible, backlit by sunlight while the moon itself glows softly in reflected Saturn-shine. 
Observations of the jets taken from various viewing geometries provide different insights into these remarkable features. Our Cassini spacecraft has gathered a wealth of information in the hopes of unraveling the mysteries of the subsurface ocean that lurks beneath the moon’s icy crust. 
This view looks toward the Saturn-facing hemisphere of Enceladus, where north is up. The image was taken in visible light with the Cassini spacecraft’s narrow-angle camera on April 13.

List nasa's Instagram Wispy arms swirling out from a bright, elongated core distinguish a particular kind of spiral galaxy known as a barred spiral, seen here in this Hubble Space Telescope image. Residing about 30 million light-years away in the northern constellation of Lynx, this galaxy was first discovered by British astronomer William Herschel over 200 years ago. 
Barred spirals are actually more common than was once thought. Around two-thirds of all spiral galaxies – including the Milky Way – exhibit these straight bars cutting through their centers. These cosmic structures act as glowing nurseries for newborn stars, and funnel material towards the active core of a galaxy. 
This galaxy is still actively forming new stars, although this process appears to be occurring very unevenly. The upper half of the galaxy – where the spiral arms are slightly better defined – hosts many more star-forming regions than the lower half, as indicated by the bright, dotted islands of light.

List nasa's Instagram One hundred years ago today, on July 17, at the dawn of humanity’s foray into to powered flight, something happened that changed forever the way humans would take to the skies. And, then the way we explore space. And, then how we study our home planet. That something was the establishment of what is now our Langley Research Center in Hampton, Virginia. Air travel, spaceflight, robotic solar-system missions: science fiction to those alive at the turn of the 20th century became science fact to those living in the 21st. America’s aerospace future has been literally made at the Langley Research Center by the best and brightest the country has to offer. 
Langley broke new ground in aeronautical research with a suite of first-of-their-kind wind tunnels that led to numerous advances in commercial, military and vertical flight, such as helicopters and other rotorcraft. Airflow turning vanes are shown here in Langley’s 16-Foot Transonic Tunnel.

List nasa's Instagram Between July 5-11, our Sun-observing satellite, the Solar Dynamics Observatory, saw a sunspot rotate into view and captured it on this. Such sunspots are a common, but are less frequent as we head toward solar minimum, which is the period of low solar activity during its regular approximately 11-year cycle. This sunspot is the first to appear after the sun was spotless for two days, and it is the only sunspot group at this moment. Like freckles on the face of the sun, they appear to be small features, but size is relative: The dark core of this sunspot is actually larger than Earth.

List nasa's Instagram In the context of space, the term ‘cloud’ can mean something rather different from the fluffy white collections of water in the sky or a way to store data or process information. Giant molecular clouds are vast cosmic objects, composed primarily of hydrogen molecules and helium atoms, where new stars and planets are born. These clouds can contain more mass than a million suns, and stretch across hundreds of light years!

The giant molecular cloud shown here is one of the closest to Earth at a distance of about 17,000 light years. Because of its relative proximity, this cloud provides astronomers with an excellent opportunity to study how stars are forming in our Milky Way galaxy.

This composite image shows the high-energy output from this stellar nursery, where X-rays from our Chandra observatory are colored blue. In about 20 hours of Chandra exposure time, over 600 young stars were detected as point-like X-ray sources, and diffuse X-ray emission from interstellar gas with a temperature of a million degrees or more was also observed. Infrared light observed with our Spitzer Space Telescope appears orange and yellow-green and shows cool gas and stars surrounded by disks of cool material.

List nasa's Instagram Seeing spots! These new, close-up images of Jupiter’s Great Red Spot reveal a tangle of dark, veinous clouds weaving their way through a massive crimson oval. The JunoCam image aboard our Juno spacecraft snapped pictures of the most iconic feature of the solar system’s largest planetary inhabitant during its Monday (July 10) flyby.

For hundreds of years, scientists have been observing, wondering and theorizing about Jupiter’s Great Red Spot. Now we have the best pictures ever of this iconic storm. It will take us some time to analyze all the data from not only JunoCam, but Juno’s eight science instruments, to shed some new light on the past, present and future of the Great Red Spot.

As planned, citizen scientists took the raw images of the flyby from the JunoCam site and processed them, providng a higher level of detail than available in their raw form. During its mission of exploration, Juno soars low over the planet’s cloud tops to probe beneath the obscuring cloud cover of Jupiter and study its auroras to learn more about the planet’s origins, structure, atmosphere and magnetosphere.

Three humans are currently living and working on the space station, conducting research and science that benefits humanity and also helps advance the exploration of our solar system.

List nasa's Instagram Dawn’s early light…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 a distance of approximately 762,000 miles from Saturn.

List nasa's Instagram On Mars, large gullies (ravines) tend to be concentrated at higher latitudes. But some gullies are on steep slopes in equatorial regions, as seen in this image. This enhanced-color close-up image shows part of the rim and inner slope of Krupac Crater located just 7.8 degrees south of the equator on the Red Planet. The colors of the gully deposits match the colors of the eroded source materials. Krupac is a relatively young impact crater, but exposes ancient bedrock.

List nasa's Instagram This zoomed-in view of Saturn’s moon Epimetheus, one of the highest resolution ever taken, shows a surface covered in craters, vivid reminders of the hazards of space. 
Epimetheus (70 miles across) is too small for its gravity to hold onto an atmosphere. It is also too small to be geologically active. That means there is no way to erase the scars from meteor impacts, except for the generation of new impact craters on top of old ones. 
This image, taken by our Cassini spacecraft was aquired at a distence of approximately 9,300 miles.

List nasa's Instagram The sun produces energy by fusing hydrogen in its core, so the layers surrounding the core generally get cooler as you move outwards—with one exception. This filament on the sun, a giant ribbon of relatively cool solar material, threads through the corona, the sun's atmosphere. The individual threads that make up the filament are clearly discernible in this photo. This image, captured by the Solar Optical Telescope onboard JAXA/NASA’s Hinode solar observatory, has made a significant step towards understanding why the corona—the outermost, wispy layer of the sun's atmosphere—is hundreds of times hotter than the lower photosphere.

List nasa's Instagram Behold a hidden galaxy! This sweeping spiral galaxy would be among the brightest in the sky were it not for its dust-obscured location. Although it is bright, the galaxy sits near the equator of the Milky Way’s galactic disk, where the sky is thick with glowing cosmic gas, bright stars, and dark, obscuring dust. In order for astronomers to see the intricate spiral structure this galaxy, they must gaze through a large amount of material contained within our own galaxy — no easy feat! 
The galaxy is very active, as indicated by the range of colors visible in this Hubble Space Telescope image, depicting the very central region of the galaxy. A beautiful mixture of hot, blue star-forming regions, redder, cooler regions of gas, and dark lanes of opaque dust can be seen, all swirling together around a bright core.
