  • Life on the Edge

    1999April 6, 2011

    NASA and educators join for a hands-on experiment designed for students of all ages to investigate life in extreme environments and to learn about the possibilities for life elsewhere in the Solar System. The program, called "Life on the Edge," begins later this month when a dogsled team will transport a collection of extreme-loving microorganisms to the summit of one of the highest mountain peaks in North America.

  • Outbursts Result in Controversy

    1999April 6, 2011

    Scientists have different ideas to explain the behavior of Soft Gamma Repeaters (SGRs). SGR's irregularly give off short blasts of radiation in the gamma ray frequencies. Magnetar theory gives an explanation, but other theories depend on the surrounding stellar environment as well as a central neutron star.

  • Unearthing Clues to Martian Fossils

    1999April 6, 2011

    The hunt for ancient life on Mars has led scientists to an other-worldly place on Earth called Mono Lake.

  • New Chandra Images Released

    1999April 6, 2011

    X-ray pictures from NASA's Chandra X-ray Observatoryreveal previously unobserved features in the remnants of three different supernova explosions.

  • Life on the Edge Update

    1999April 6, 2011

    A team of sled dogs has braved spring storms and wily marmots to recover microbes from a California mountain top. Yeast samples exposed to extreme conditions near the White Mountain summit will be distributed to classrooms as part of NASA's Life on the Edge education initiative.

  • The search for life on Mars will begin in Siberia

    1999April 6, 2011

    Russian and Marshall scientists will look for life forms in the inhospitable realm of Siberian permafrost. The scientists hope to broaden our understanding of "extremophiles" - forms of life that exist under extreme conditions - which will help in the search for life on other planets.

  • Postmortems in the Sky

    1999April 6, 2011

    To say they are ghoulish may be going too far, but like ghouls those studying Gamma Ray Bursts gleefully seek the moldering remains, and never see the living victim. But they are very much interested in both the victim and the cause.

  • Gamma-ray Burststo take center stage at international meeting

    1999April 6, 2011

    More than 200 astronomers will gather to talk about gamma-ray bursts, one of the most mysterious and increasingly watched-for phenomena in the universe. The 5th Huntsville Gamma Ray Burst Symposium, to be held Oct 18-22 in Huntsville, Alabama, will have a wealth of new observations for discussions of bursts and how to study them.

  • A Swift Look at the Biggest Explosions in the Universe

    1999April 6, 2011

    Spurred by the thousands of Gamma-ray Burstsrecorded over the last three decades, NASA is planning missions dedicated to discovering the causes of what had been an oddity and now has become a primary mystery in astronomy.

  • Through the Looking Glass

    1999April 6, 2011

    NASA's Hubble Space Telescope has discovered exotic rings, arcs and crosses that are optical mirages produced by gigantic gravitational lenses in deep space.
