Enormous arms of hot gas have been discovered in the Coma cluster of galaxies by using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. These features, which span at least half a million light years, provide insight into how the Coma cluster has grown through mergers of smaller groups and clusters of galaxies to become one of the largest structures in the universe held together by gravity. A new composite image, with Chandra data in pink and optical data from the Sloan Digital Sky Survey appearing in white and blue, features these spectacular arms. In this image, the Chandra data have been processed so extra detail can be seen. The X-ray emission is from multimillion-degree gas and the optical data shows galaxies in the Coma Cluster, which contain only about one-sixth the mass in hot gas. Only the brightest X-ray emission is shown here, to emphasize the arms, but the hot gas is present over the entire field of view. Researchers think that these arms were most likely formed when smaller galaxy clusters had their gas stripped away by the head wind created by the motion of the cluster through the hot gas, in much the same way that the headwind created by a roller coaster blows the hats off riders.

Aboard the International Space Station, NASA astronaut Karen Nyberg caught the reflection of Earth's horizon on the station’s solar arrays at sunset on Sept. 18. The space station is a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. The space station has had continuous human occupation since November 2000. In that time it has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to NASA's next great leap in exploration, including future missions to an asteroid and Mars.

A United States flag is flown at half-staff just outside the Mid-Atlantic Regional Spaceport Pad-0A with the Orbital Sciences Corporation Antares rocket, Tuesday, Sept. 17, 2013, NASA Wallops Flight Facility, Virginia. President Obama directed Monday that flags be lowered to half-staff to pay tribute to the victims of "the senseless acts of violence" perpetrated at the Washington Navy Yard. NASA's commercial space partner, Orbital Sciences Corporation, is targeting a Sept. 18 launch for its demonstration cargo resupply mission to the International Space Station between 10:50 and 11:05 a.m. EDT. The demonstration flight to the International Space Station will deliver about 1,300 pounds of cargo, including food and clothing, to the Expedition 37 crew.

Tropical Storm Man-yi covered two-thirds of the big island of Japan when NASA's Terra satellite passed overhead and captured a visible image on Sept. 16 at 0140 UTC/Sept. 15 at 9:40 p.m. EDT. Man-yi took just a day to cross over Japan before exiting into the northwestern Pacific Ocean. The Joint Typhoon Warning Center forecast track on Sept. 16 takes Man-yi into the Sea of Okhotsk by Sept. 17. Man-yi strengthened to a typhoon just before making landfall. It dropped heavy rainfall totals, created flooding in Kyoto, damaged homes and killed two people, according to the Associated Press. The Shiga and Fukui Prefectures reported mudslides. When Man-yi made landfall, it had maximum sustained winds near 100 mph (162 kph). According to the Japanese Meteorological Agency, Man-yi was dropping as much as 3 inches/76 mm of rain per hour.

This image of the Earth shows us that we live on a dynamic, restless planet. On any given day, there is usually a cyclone, tropical depression, or extra-tropical storm brewing somewhere on the Earth. But for a brief moment this week, the skies over all of the oceans were relatively calm. This image is a composite of fourteen polar satellite passes, or swaths, stitched together from September 8, 2013. The natural-color images were acquired by the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi National Polar-orbiting Partnership (Suomi NPP) satellite. At the time of those near-midday passes, there were no hurricanes, cyclones, or tropical storms in the Atlantic, Pacific, or Indian Ocean basins—a relatively rare occurrence at the height of the hurricane/cyclone season in the northern hemisphere. There was plenty of cloud cover, of course, and smaller storm systems. In the eastern Pacific, remnants of tropical storm Lorena were breaking up near the Baja Peninsula. In the eastern Atlantic, the pieces of tropical depression #9 were starting to gather near the islands of Cape Verde; by the next day, tropical storm Humberto would form.

Four RS-25 engines, like the one pictured here undergoing a hot-fire test, will power the core stage of NASA's Space Launch System (SLS) -- NASA's new heavy-lift launch vehicle. Towering more than 200 feet tall with a diameter of 27.6 feet, the core stage will store cryogenic liquid hydrogen and liquid oxygen that will feed the vehicle’s RS-25 engines. SLS will be the most powerful rocket in the world with the greatest capacity of any launch system ever built to support any destination, any payload and any mission, including NASA's plans to send humans to a captured and relocated asteroid. The 70-metric-ton (77-ton) configuration will stand at 321 feet -- taller than the Statue of Liberty.

Orbital Sciences rolled out its Antares rocket and Cygnus spacecraft to the Mid-Atlantic Regional Spaceport Pad-0A at NASA's Wallops Flight Facility in Virginia on Friday morning, Sept. 13, 2013. The Antares is scheduled to launch Cygnus at 11:16 a.m. EDT on Tuesday, Sept. 17 on a demonstration cargo resupply mission to the International Space Station. Cygnus will deliver about 1,300 pounds (589 kilograms) of cargo, including food and clothing, to the Expedition 37 crew aboard the space station, who will capture and install the spacecraft on Sept. 22 using the station's robotic arm. Orbital is building and testing its Antares rocket and Cygnus spacecraft under NASA’s Commercial Orbital Transportation Services (COTS) program. Following a successful demonstration mission, Orbital is poised to begin eight cargo flights contracted by NASA to resupply the station. Future flights of Cygnus will significantly increase NASA's ability to deliver new science investigations to the nation's only laboratory in microgravity.
