Members of the STS-129 shuttle mission present a specially minted silver medallion to National Football League officials on Wednesday, Jan. 27, 2010, at the Pro Football Hall of Fame in Canton, Ohio. The coin, which was flown in space during the November flight of Atlantis, will be used for the official coin toss prior to [...]

On Jan. 7, 1610, Galileo Galilei’s improvements to the telescope enabled humanity to see Jupiter’s four largest moons for the first time. Io, Europa, Ganymede and Callisto–the so-called Galilean satellites–were seen by the Long Range Reconnaissance Imager on the New Horizons spacecraft during its flyby of Jupiter in late February 2007. The images have been [...]
Wishing all a joyful new year, members of the Cassini-Huygens team offer us their views of Saturn and the Cassini spacecraft. Cassini-Huygens, a cooperative project of NASA, the European Space Agency and the Italian Space Agency, which is managed by the Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, for [...]

As interest in Earth’s changing climate heats up, a tiny dark particle is stepping into the limelight: black carbon. Commonly known as soot, black carbon enters the air when fossil fuels and biofuels, such as coal, wood, and diesel are burned. Black carbon is found worldwide, but its presence and impact are particularly strong in [...]
NASA’s Wide-field Infrared Survey Explorer, or WISE, launched aboard a United Launch Alliance Delta II rocket at 9:09 a.m. EST from Space Launch Complex-2 at Vandenberg Air Force Base. WISE will scan the entire sky in infrared light, picking up the glow of hundreds of millions of objects and producing millions of images. Image Credit: [...]
A scaffolding structure built around NASA’s Wide-field Infrared Survey Explorer, or WISE, allows engineers to freeze its hydrogen coolant. The WISE infrared instrument is kept extremely cold by a bottle-like tank filled with frozen hydrogen, called the cryostat. The cryostat can be seen at the top of the spacecraft.

This artist’s concept illustrates the two types of spiral galaxies that populate our universe: those with plump middles, or central bulges (upper left), and those lacking the bulge (foreground). New observations from NASA’s Spitzer Space Telescope provide strong evidence that the slender, bulgeless galaxies can, like their chubbier counterparts, harbor supermassive black holes at their [...]
Off the east coast of New Zealand, cold rivers of water that have branched off from the Antarctic Circumpolar Current flow north past the South Island and converge with warmer waters flowing south past the North Island. The surface waters of this meeting place are New Zealand’s most biologically productive. This image of the area [...]
