RAPTOR Images GRB 021211
| Title |
RAPTOR Images GRB 021211 |
| Explanation |
On December 11 astronomers found [ http://www.raptor.lanl.gov/ NoFrame_Archive.htm ] one of the brightest and most distant explosions in the Universe - a gamma-ray burst [ http://science.msfc.nasa.gov/ newhome/headlines/ast26mar99_1.htm ] - hiding in the glare of a relatively nearby star. The earliest image of the burst's visible light was caught by an earthbound RAPTOR [ http://www.raptor.lanl.gov/ ] (RAPid Telescopes for Optical Response). The two exposures inset above were taken by a RAPTOR unit about 65 seconds (left) and 9 minutes (top right) after high-energy radiation from the burst, dutifully cataloged as GRB 021211 [ http://space.mit.edu/HETE/Bursts/ GRB021211/ ], was identified by the orbiting HETE-2 satellite [ http://space.mit.edu/HETE/ ]. One of only two optical transients (OTs) ever found [ http://science.nasa.gov/newhome/headlines/ ast27jan99%5F1.htm ] at times so close to a burst's gamma-ray emission [ http://www.pbs.org/wgbh/nova/gamma/milkyway.html ], the fading visible light source is indicated by arrows, blended with the image of foreground stars toward the constellation Canis Minor [ http://www.starshine.com/frankn/astronomy/ skychart.asp?abbr=CMI ]. The RAPTOR unit (lower inset) is designed with peripheral low resolution cameras and a central, sensitive high resolution imager, in analogy with a predator's vision [ http://www.raptor.lanl.gov/ NoFrame_SysOverview.htm ]. In the future, the RAPTOR project expects its innovative instruments to be able to independently discover and catalog a host of cosmic things that go bump in the night [ http://antwrp.gsfc.nasa.gov/apod/ap020228.html ]. |
