... A Powerful Gamma Ray Burst . ... Credit: S. R. Kulkarni, S. G. Djorgovski ( Caltech ), the Caltech GRB Team , NASA Explanation: Gamma-ray bursts are thought to be the most powerful explosions in the Universe, yet the cause of these high-energy flashes remains a mystery . Blindingly bright for space-based gamma-ray detectors the burst sources are so faint at visible wavelengths that large telescopes and sensitive cameras are required to search for them. ...

... Afterglow . ... Explanation: This sequence of three false color X-ray pictures from the Italian/Dutch BeppoSAX satellite follows the fading glow from a gamma-ray burster . This burster triggered orbiting gamma-ray observatories on December 14, 1997 and within 6.5 hours the sensitive X-ray cameras onboard BeppoSAX had been turned to record the first image (left) of the afterglow. ... The first two pictures were taken 6 hours apart, while the final picture was made 2 days after the gamma-ray burst. ...
