Starry, Starry Sky from the Space Station: An Expedition 41 crew member aboard the Earth-orbiting International Space Station on Sept. 13, 2014, captured this image of a starry sky. The white panel at left belonging to the ATV-5 spacecraft, which is docked with the orbital outpost, obstructs the view of Scorpius. The red star Antares is directly to the left of the bottom of the second ATV panel from the top. The two stars that are close together and on the lower left of the photo comprise Shaula, the tip of the scorpionâ€s tail. The open cluster close to Shaula is M7. The hardware at bottom right is part of one of the station's solar panels. Image Credit: NASA #nasa #esa #atv #iss #spacestation #exp41 #earth #stars #space #science; -
Hubble Feathers the Peacock: This picture, taken by our Hubble Space Telescope's Wide Field Planetary Camera 2 (WFPC2), shows a galaxy known as NGC 6872 in the constellation of Pavo (The Peacock). Its unusual shape is caused by its interactions with the smaller galaxy that can be seen just above NGC 6872, called IC 4970. They both lie roughly 300 million light-years away from Earth. From tip to tip, NGC 6872 measures over 500,000 light-years across, making it the second largest spiral galaxy discovered to date. In terms of size it is beaten only by NGC 262, a galaxy that measures a mind-boggling 1.3 million light-years in diameter! To put that into perspective, our own galaxy, the Milky Way, measures between 100,000 and 120,000 light-years across, making NGC 6872 about five times its size.

Our Airborne Campaigns Focus on Climate Impacts in the Arctic: This red plane is a DHC-3 Otter, the plane flown in our Operation IceBridge-Alaska surveys of mountain glaciers in Alaska. Over the past few decades, average global temperatures have been on the rise, and this warming is happening two to three times faster in the Arctic. As the region's summer comes to a close, We're hard at work studying how rising temperatures are affecting the Arctic. Our researchers this summer and fall are carrying out three Alaska-based airborne research campaigns aimed at measuring greenhouse gas concentrations near Earth's surface, monitoring Alaskan glaciers, and collecting data on Arctic sea ice and clouds. Observations from these campaigns will give researchers a better understanding of how the Arctic is responding to rising temperatures.

Our Hubble Space Telescope finds big surprise in teeny tiny galaxy: A supermassive black hole with a mass 21 million times our sun. The black hole is five times the mass of the one at the center of our Milky Way galaxy. It is inside one of the densest galaxies known to date -- the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter. If you lived inside this dwarf galaxy, the night sky would dazzle with at least 1 million stars visible to the naked eye. Our nighttime sky as seen from Earth’s surface shows 4,000 stars. This is an artist's view of M60-UCD1 black hole. Image Credit: NASA, ESA, STScI-RCC14-41a #nasa #space #galaxy #milkyway #blackhole #astronomy #stars #hubble #hst #telescope #science;

Powerful, Pulsating Core of Star: Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars. The blue dot in this image marks the spot of an energetic pulsar -- the magnetic, spinning core of star that blew up in a supernova explosion. We discovered the pulsar by identifying its telltale pulse -- a rotating beam of X-rays, that like a cosmic lighthouse, intersects Earth every 0.2 seconds. The pulsar lies in our inner Milky Way galaxy about 42,000 light-years away. Image credit: NASA/JPL-Caltech/SAO #nustar #nasa #space #astronomy #galaxy #star #xray #milkyway #science; -
Florida to Louisiana Viewed From the International Space Station: NASA astronaut Reid Wiseman captured this image of Florida to Louisiana just before dawn, taken from the space station, and posted it to social media on Friday, Sept. 12. Wiseman, Commander Max Suraev and Flight Engineer Alexander Gerst began their first full workweek Monday as a three-person crew aboard the station, while the three additional flight engineers who will round out the Expedition 41 crew spent the day training for next week’s launch to the orbiting complex.

We're poised to announce the final phase of development and certification to provide safe, reliable and cost-effective transportation to and from the International Space Station from the U.S. on American systems. We will make a major announcement today at 4 p.m. EDT regarding the return of human spaceflight launches to the United States. Whoever is chosen will have the goal to achieve certification of the system – including a test flight to the International Space Station with a NASA astronaut -- in 2017, returning a critical capability to America and greatly expanding the scientific research potential of the orbiting laboratory. Watch the announcement live on NASA TV. Image Credit: NASA #launchamerica #journeytomars #nasa #iss #spacestation #astronauts; -
Aboard the space station (@ISS), astronaut Reid Wiseman snapped this photo Sunday, Sept. 14. and wrote, "Nothing like a view of the #MilkyWay first thing on Sunday morning. Beautiful." The crew began their first full workweek Monday as a three-person crew aboard the space station, while the three additional flight engineers who will round out the Expedition 41 crew spent the day training for next week's launch to the orbiting complex.

Crescent Mimas: A thin sliver of Mimas is illuminated, the long shadows showing off its many craters, indicators of the moon's violent history. The most famous evidence of a collision on Mimas (246 miles, or 396 kilometers across) is the crater Herschel that gives Mimas its Death Star-like appearance. This view looks toward the anti-Saturn hemisphere of Mimas. North on Mimas is up and rotated 40 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 20, 2013. The view was acquired at a distance of approximately 100,000 miles (200,000 kilometers) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 130 degrees. Image scale is 4,000 feet (1 kilometer) per pixel. Credit: NASA/JPL-Caltech/Space Science Institute #nasa #space #moon #mimas #saturn #cassini #planets #science;

We commemorate the 200th Anniversary of the raising of the American flag over Fort McHenry in Baltimore, Maryland, on Sept. 14, 1814 which inspired Francis Scott Key to scribe 'The Defence of Fort M'Henry' which became the lyrics of our national anthem. As our nation celebrates the 200th anniversary of our national anthem, we remember the original inspiration for Francis Scott Key's immortal verse, "O say can you see by the dawn's early light ..." An adult osprey, carrying a fish in its talons, prepares to land in its nest atop a speaker platform in the Press Site parking lot at NASA's Kennedy Space Center in Florida.

We all know that it's what's on the inside that counts, right? But sometimes what's outside can be just as important. At least that's the case with the International Space Station (ISS) and the collection of external instruments soon to join those already operating in orbit. Moving at 17,500 miles per hour and operating around 240 miles above Earth, the space station circles at a 51.6 degree inclination north and south of the equator, offering a unique platform to mount research equipment. The space station's orbit circles the globe 16 times daily to cover more ground at different times of day, while other satellites follow a sun-synchronous orbit-crossing the equator at the same local time every revolution. For this reason, data from station-mounted instruments can complement those gathered from similar satellite missions to fill in gaps for greater scientific returns. A view of Earth's atmosphere from the International Space Station during Expedition 23 illustrates the unique vantage point the orbiting laboratory provides for externally mounted instruments.

World's Largest Spacecraft Welding Tool for Space Launch System (@explorenasa): The largest spacecraft welding tool in the world, the Vertical Assembly Center, officially is open for business at NASA's Michoud Assembly Facility in New Orleans. The 170-foot-tall, 78-foot-wide giant completes a world-class welding toolkit that will be used to build the core stage of America's next great rocket, the Space Launch System. SLS will be the most powerful rocket ever built for deep space missions, including to an asteroid and eventually Mars. The core stage, towering more than 200 feet tall (61 meters) with a diameter of 27.6 feet (8.4 meters), will store cryogenic liquid hydrogen and liquid oxygen that will feed the rocket's RS-25 engines.

Hubble Paints a Spattering of Blue: Far beyond the stars in the constellation of Leo (The Lion) is irregular galaxy IC 559. With its irregular shape and bright blue spattering of stars, it is a fascinating galactic anomaly. It may look like sparse cloud, but it is in fact full of gas and dust which is spawning new stars. Discovered in 1893, IC 559 lacks the symmetrical spiral appearance of some of its galactic peers and not does not conform to a regular shape. It is an irregular galaxy with some evidence for a spiral structure. Irregular galaxies make up about a quarter of all known galaxies and do not fall into any of the regular classes of the Hubble sequence. Most of these uniquely shaped galaxies were not always so - IC 559 may have once been a conventional spiral galaxy that was then distorted and twisted by the gravity of a nearby cosmic companion.
