NASA's Galaxy Evolution Explorer has discovered a galaxy tail studded with bright knots of new stars. The tail, which was created as the galaxy IC 3418 plunged into the neighboring Virgo cluster of galaxies, offers new insight into how stars form. "The gas in this galaxy is being blown back into a turbulent wake," said Janice Hester of the California Institute of Technology in Pasadena, lead author of a recent study published in the Astrophysical Journal Letters. "The gas is like sand caught...

GREENBELT, Md., June 14 /PRNewswire-USNewswire/ -- The Solar X-Ray Imager instrument aboard the GOES-15 satellite has just provided its first light image of the sun, but it required a lot of experts to make it happen. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Scientists and engineers from NASA and the National Oceanic and Atmospheric Administration (NOAA) have been working to bring the Solar X-Ray Imager (SXI) instrument to full functionality since the Geostationary...

In its first five years in orbit, NASA's Swift satellite has given astronomers more than they could have hoped for. Its discoveries range from a nearby nascent supernova to a blast so far away that it happened when our universe was only 5 percent of its present age. Swift primarily studies gamma-ray bursts (GRBs) -- the biggest and most mysterious explosions in the cosmos. On April 13, the spacecraft's "burst-o-meter" cataloged its 500th GRB. "On the one hand, it's just a number, but on the...

Mission engineers and scientists with NASA's Galaxy Evolution Explorer, a space telescope that has been beaming back pictures of galaxies for three times its design lifespan, are no longer planning science observations around one of its two ultraviolet detectors. "The remaining, near-ultraviolet detector is still busy probing galaxies both nearby and distant," said Kerry Erickson, the mission's project manager at NASA's Jet Propulsion Laboratory in Pasadena. "We've got lots of science data...

NASA has extended a contract with the Smithsonian Astrophysical Observatory in Cambridge, Mass., to provide science and operational support for the Chandra X-ray Observatory, a powerful tool used to better understand the structure and evolution of the universe. The contract extension with the Smithsonian Astrophysical Observatory provides continued science and operations support to Chandra. This approximately $172 million modification brings the total value of the contract to approximately...

A network of cameras deployed around the Arctic in support of NASA's THEMIS mission has made a startling discovery about the Northern Lights. Sometimes, vast curtains of aurora borealis collide, producing spectacular outbursts of light. Movies of the phenomenon were unveiled at the Fall meeting of the American Geophysical Union today in San Francisco. "Our jaws dropped when we saw the movies for the first time," says space scientist Larry Lyons of UCLA, a leading member of the team that made...

NASA's Wide-field Infrared Survey Explorer, or Wise, is now perched atop its rocket at Vandenberg Air Force Base, north of Santa Barbara, Calif. The mission, which will scan the whole sky in infrared light, is scheduled to blast off on Dec. 9. It was hoisted to the top of its United Launch Alliance Delta II rocket on Friday, Nov. 20. JPL manages the Wide-field Infrared Survey Explorer for NASA's Science Mission Directorate, Washington. The mission's principal investigator, Edward Wright, is...

NASA's Cosmic Background Explorer (COBE) satellite rocketed into Earth orbit on Nov. 18, 1989, and quickly revolutionized our understanding of the early cosmos. Developed and built at Goddard Space Flight Center in Greenbelt, Md., COBE precisely measured and mapped the oldest light in the universe -- the cosmic microwave background. COBE showed that the radiation's spectrum agrees exactly with predictions based on the Big Bang theory. And COBE's map of slight hot and cold spots within this...

PALO ALTO, Calif., Oct. 15 /PRNewswire/ -- Nearly a year ago - on October 19, 2008 - the Interstellar Boundary Explorer (IBEX) - a NASA Small Explorer Mission - was launched into Earth orbit to discover the global interaction between the solar wind and the interstellar medium - the gas, dust and radiation environment between the stars - by measuring the neutral atoms created by that interaction. As our Sun travels through the galaxy it is encompassed in a giant bubble inflated by a...
