Now, astronomers at NASA's Goddard Space Flight Center in Greenbelt, Md., find that an X-ray source in galaxy NGC 5408 represents one of the best cases for a middleweight black hole to date. id_31 10 Nov 2009 http://www.nasa.gov/mission_pages/swift/bursts/uv_andromeda.html In a break from its usual task of searching for distant cosmic explosions, NASA's Swift satellite has acquired the highest-resolution view of a neighboring spiral galaxy ever attained in the ultraviolet. The galaxy, known as M31 in the constellation Andromeda, is the largest and closest spiral galaxy to our own. id_30 16 Sep 2009 http://swift.gsfc.nasa.gov/docs/swift/proposals/swiftgi.html Details on the Swift Cycle 6 Guest Investigator Program are now available. id_29 27 Jul 2009 http://www.nasa.gov/topics/universe/features/keck_burst.html Gamma-ray bursts are the universe's biggest explosions, capable of producing so much light that ground-based telescopes easily detect it billions of light-years away. Yet, for more than a decade, astronomers have puzzled over the nature of so-called dark bursts, which produce gamma rays and X-rays but little or no visible light. They make up roughly half of the bursts detected by NASA's Swift satellite since its 2004 launch. id_28 8 Jun 2009 http://swift.gsfc.nasa.gov/docs/swift/news/2009/swift_softwarev3.3_caldb.html New Release of the Swift Software and Calibration Data is Available for Download. id_27 3 Jun 2009 http://www.nasa.gov/mission_pages/swift/bursts/cosmic_record.html NASA's Swift satellite and an international team of astronomers have found a gamma-ray burst from a star that died when the universe was only 630 million years old, or less than five percent of its present age. The event, dubbed GRB 090423, is the most distant cosmic explosion ever seen. id_26 28 Apr 2009 http://swift.gsfc.nasa.gov/docs/swift/news/2009/swift_softwarev3.2_caldb.html New Release of the Swift Software and Calibration Data is Available for Download. id_25 7 Apr 2009 http://www.nasa.gov/mission_pages/swift/bursts/observatory_webcast.html A montage of comet images made using NASA's Swift spacecraft illustrates just how different three comets can be. The images, including a never-released image of Comet 8P/Tuttle, were shown today during a live, 24-hour video webcast called "Around the World in 80 Telescopes." Organized by the European Southern Observatory headquartered in Garching, Germany, the webcast is part of the 100 Hours of Astronomy project, a worldwide celebration of astronomy running through April 5. id_24 3 Apr 2009 http://swift.gsfc.nasa.gov/docs/swift/proposals/c5_acceptarg.html Cycle 5 Results id_23 24 Feb 2009 http://www.nasa.gov/mission_pages/swift/bursts/lulin.html While waiting for high-energy outbursts and cosmic explosions, NASA's Swift Gamma-ray Explorer satellite is monitoring Comet Lulin as it closes on Earth. For the first time, astronomers are seeing simultaneous ultraviolet and X-ray images of a comet. id_22 20 Feb 2009 http://www.nasa.gov/mission_pages/swift/bursts/gammaray_fireworks.html Astronomers using NASA's Swift satellite and Fermi Gamma-ray Space Telescope are seeing frequent blasts from a stellar remnant 30,000 light-years away. id_21 10 Feb 2009
