Gamma-ray birth cries suggest massive magnetic engines
03-08-2007 · EurekAlert!A gamma-ray burst observed by NASA's Swift satellite on July 29, 2006, generated an X-ray afterglow that remained detectable to the spacecraft's X-ray Telescope (XRT) for 125 days -- an astonishing long time -- indicating the possible formation of a magnetar. If Chandra or XMM-Newton can see the afterglow later this year, GRB 060729 will break the record for longest observed X-ray afterglow.

- Controlled by distant explosions
03-28-2007 · EurekAlert!
A time-series of high-resolution spectra in the optical and ultraviolet has twice been obtained just a few minutes after the detection of a gamma-ray bust explosion in a distant galaxy. The international team of astronomers responsible for these observations derived new conclusive evidence about the nature of the surroundings of these powerful explosions linked to the death of massive stars.

- Intergalactic 'shot in the dark' shocks astronomers
12-18-2007 · EurekAlert!
A team of astronomers has discovered a cosmic explosion that seems to have come from the middle of nowhere -- thousands of light-years from the nearest galaxy-sized collection of stars, gas, and dust. This "shot in the dark" is surprising because the type of explosion, a long-duration gamma-ray burst, is thought to be powered by the death of a massive star.

- Two cosmic bursts upset tidy association between long gamma-ray bursts and supernovae
12-20-2006 · EurekAlert!
Only in the past decade have astronomers been able to make sense of the bright flashes of cosmic light known as gamma-ray bursts, which are the brightest explosions in the universe. But two newly observed bursts reported in this week's Nature suggest that not all can be neatly divided between long bursts associated with supernovae and short bursts due to stellar mergers.

- X-ray satellites catch magnetar in gigantic stellar 'hiccup'
04-04-2007 · European Space Agency (ESA)
Astronomers using data from several X-ray satellites have caught a magnetar – the remnant of a massive star with an incredibly strong magnetic field – in a sort of giant cosmic blench.

- Gamma-ray burst challenges theory
03-08-2007 · EurekAlert!
In a series of landmark observations gathered over a period of four months, NASA's Swift satellite has challenged some of astronomers' fundamental ideas about gamma-ray bursts (GRBs), which are among the most extreme events in our universe. GRBs are the explosive deaths of very massive stars, some of which eject jets that can release in a matter of seconds the same amount of energy that the sun will radiate over its 10-billion-year lifetime.

- Mystery cosmic explosions
12-20-2006 · EurekAlert!
Scientists have discovered what appears to be a new kind of cosmic explosion, the subject of four articles in this week's issue of Nature. They call the explosion a hybrid gamma-ray burst.As with other gamma-ray bursts, this hybrid burst is likely signalling the birth of a new black hole. It is unclear, however, what kind of object or objects exploded or merged to create the black hole or, perhaps, something even more bizarre.

- New algorithms from UCSD improve automated image labeling
03-29-2007 · EurekAlert!
Electrical engineers from UC San Diego have made progress on a different kind of image search engine -- one that analyzes the images themselves. This approach may be folded into next-generation image search engines for the Internet; and in the shorter term, could be used to annotate and search commercial and private image collections.

- Astronomers discover new kind of black-hole explosion
12-20-2006 · EurekAlert!
Scientists have discovered what appears to be a new kind of cosmic explosion -- a "hybrid gamma-ray burst" -- which will be the subject of four articles to be published in the journal Nature on 21 December 2006. The scientists include four astrophysicists at Penn State University as well as others around the globe. The nature of the explosion is a puzzle in "virtually uncharted territory" for space scientists.

- NASA's Chandra sees brightest supernova ever
05-07-2007 · EurekAlert!
The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes. This discovery indicates that violent explosions of extremely massive stars were relatively common in the early universe, and that a similar explosion may be ready to go off in our own Galaxy.

- Iowa State astrophysicists provide the eyes for new gamma ray telescope system
04-19-2007 · EurekAlert!
Iowa State University researchers built the four cameras for the VERITAS telescope system in Arizona. The new $20 million telescope system detects gamma rays and will help astrophysicists explore distant regions of space, look for evidence of dark matter and help explain the origins of the most energetic radiation in the universe.
