An Odd Trio: The Cassini spacecraft captures a rare family photo of three of Saturn's moons that couldn't be more different from each other! As the largest of the three, Tethys (image center) is round and has a variety of terrains across its surface. Meanwhile, Hyperion (to the upper-left of Tethys) is the "wild one" with a chaotic spin and Prometheus (lower-left) is a tiny moon that busies itself sculpting the F ring. This view looks toward the sunlit side of the rings from about 1 degree above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 14, 2014. The view was acquired at a distance of approximately 1.2 million miles (1.9 million kilometers) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 22 degrees. Image scale is 7 miles (11 kilometers) per pixel.

Now Orbiting Mars! After a 10-month, 442 million mile journey, our Mars Atmosphere and Volatile Evolution (MAVEN) arrived in Mars orbit late Sunday. It is the first spacecraft dedicated to exploring the upper atmosphere of Mars, answering important questions about the planet's history and climate.

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.

Space station's Expedition 41 crew focused on eye exams and scientific research aboard the orbiting complex Thursday while continuing preparations for the arrival of the other half of their crew next week. Photographed with a mounted automated camera, this is one of a number of images featuring the European Space Agency's fifth Automated Transfer Vehicle docked with the station.

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;
