Before drifting off to sleep, NASA astronaut Scott Kelly (@stationcdrkelly) captured this images from the International Space Station and wrote, " Day 180. Moonlight over Italy. #BuonaNotte Good night from @ISS! #YearInSpace." Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission. Traveling the world about 250 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day. Image Credit: NASA #nasa #spacestation #space #earth #iss; -
The film "The Martian" is set in the 2030s, when our astronauts are regularly traveling to Mars and living on the surface. Right now, we're developing the capabilities needed to send humans to the Red Planet. A fleet of robotic spacecraft and rovers already are on and around Mars, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back radiation data from the surface. This data will help us plan how to protect the astronauts who will explore Mars. Future missions like the Mars 2020 rover, seeking signs of past life, also will demonstrate new technologies that could help astronauts survive on Mars.

Our New Horizons spacecraft has returned the best color and the highest resolution images yet of Pluto's largest moon, Charon - and these pictures show a surprisingly complex and violent history. This high-resolution enhanced color view of Charon was captured just before closest approach on July 14. The image combines blue, red and infrared images; the colors are processed to best highlight the variation of surface properties across Charon. Charon's color palette is not as diverse as Pluto's; most striking is the reddish north (top) polar region, informally named Mordor Macula. Charon is 754 miles (1,214 kilometers) across; this image resolves details as small as 1.8 miles (2.9 kilometers). Many scientists expected Charon to be a monotonous, crater-battered world; instead, they're finding a landscape covered with mountains, canyons, landslides, surface-color variations and more.

A Fresh Perspective on an Extraordinary Cluster of Galaxies: Galaxy clusters are huge conglomerations of galaxies, hot gas, and dark matter and represent the largest structures in the universe held together by gravity. The Phoenix Cluster, pictured here, has shattered multiple records in the past: In 2012, scientists announced that the Phoenix cluster featured the highest rate of cooling hot gas and star formation ever seen in the center of a galaxy cluster, and is the most powerful producer of X-rays of all known clusters. The rate at which hot gas is cooling in the center of the cluster is also the largest ever observed. New observations of this galaxy cluster are helping astronomers better understand this remarkable object. Data reveal narrow filaments from the center of the cluster where stars are forming. These massive cosmic threads of gas and dust, most of which had never been detected before, extend for 160,000 to 330,000 lights years. This is longer than the entire breadth of the Milky Way galaxy, making them the most extensive filaments ever seen in a galaxy cluster. Image credit: X-ray: NASA/CXC/MIT/M.

Solar Loops: An active region viewed in profile put on quite a show of erupting plasma and looping arches on Sept. 22-23. The loops, seen above the sun's surface on the right, are light emissions from charged particles spinning along magnetic field lines that dance through the sun's atmosphere. The region, which appeared as a sunspot group in visible light, was observed here in two wavelengths of extreme ultraviolet light over a period of about 40 hours. Though invisible to our eyes, light emissions in the extreme ultraviolet wavelength of 171 Angstroms are typically colorized in gold, while emissions in 304 angstroms are colorized in red.

Water on Mars! New findings from our Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Dark, narrow streaks on Martian slopes such as these at Hale Crater are inferred to be formed by seasonal flow of water on contemporary Mars. The streaks are roughly the length of a football field. The imaging and topographical information in this processed, false-color view. These dark features on the slopes are called "recurring slope lineae" or RSL. Planetary scientists detected hydrated salts on these slopes at Hale Crater, corroborating the hypothesis that the streaks are formed by briny liquid water.

It's a #SuperBloodMoon! A perigee full moon, or supermoon, is seen behind the Washington Monument during a total lunar eclipse on Sunday, Sept. 27, in Washington, DC. The combination of a supermoon and total lunar eclipse last occurred in 1982 and will not happen again until 2033.

This new image of the spiral galaxy NGC 3521 from the NASA/ESA Hubble Space Telescope is not out of focus. Instead, the galaxy itself has a soft, woolly appearance as it a member of a class of galaxies known as flocculent spirals. Like other flocculent galaxies, NGC 3521 lacks the clearly defined, arcing structure to its spiral arms. In flocculent spirals, fluffy patches of stars and dust show up here and there throughout their disks. Sometimes the tufts of stars are arranged in a generally spiraling form, as with NGC 3521, but illuminated star-filled regions can also appear as short or discontinuous spiral arms. NGC 3521 is located almost 40 million light-years away in the constellation of Leo (The Lion). Image credit: ESA/Hubble & NASA and S.

The Rich Color Variations of Pluto" Our New Horizons spacecraft captured this high-resolution enhanced color view of Pluto during its July 14, 2015 #PlutoFlyby. The image combines blue, red and infrared images taken by the Ralph/Multispectral Visual Imaging Camera (MVIC). Pluto's surface sports a remarkable range of subtle colors, enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a complex geological and climatological story that scientists have only just begun to decode.

This is the expanding remains of a massive star that exploded about 8,000 years ago. Called the Veil Nebula, the debris is one of the best-known supernova remnants, deriving its name from its delicate, draped filamentary structures. The entire nebula is 110 light-years across, covering six full moons on the sky as seen from Earth, and resides about 2,100 light-years away in the constellation Cygnus, the Swan. This view is a mosaic of six pictures from our Hubble Space Telescope of a small area roughly two light-years across, covering only a tiny fraction of the nebula's vast structure. This close-up look unveils wisps of gas, which are all that remain of what was once a star 20 times more massive than our sun. The fast-moving blast wave from the ancient explosion is plowing into a wall of cool, denser interstellar gas, emitting light. The nebula lies along the edge of a large bubble of low-density gas that was blown into space by the dying star prior to its self-detonation.

A bright light source and/or speckled background – such as the sun or moon – is necessary for visualizing aerodynamic flow phenomena generated by aircraft or other objects passing between the observer’s camera and the backdrop. This patent-pending method, made possible by improved image processing technology, is called Background-Oriented Schlieren using Celestial Objects, or BOSCO. Flow visualization is one of the fundamental tools of aeronautics research, and schlieren photography has been used for many years to visualize air density gradients caused by aerodynamic flow. Traditionally, this method has required complex and precisely aligned optics as well as a bright light source. Refracted light rays revealed the intensity of air density gradients around the test object, usually a model in a wind tunnel. Capturing schlieren images of a full-scale aircraft in flight was even more challenging due to the need for precise alignment of the plane with the camera and the sun. Using the solar disk as a backdrop, this image reveals details using a calcium-K optical filter. Researchers processed this image to reveal shock waves created by a supersonic T-38C.
