Scientists Image Gamma Ray Burst As It Occurs
News story originally written on January 30, 1999
Last week scientists were able to take the first pictures of a gamma ray burst
while it was occuring.
In just 22 seconds after detection of the burst by the Burst and
Transient Source Experiment (BATSE) aboard the Compton Gamma Ray
Observatory, scientists with the Robotic Optical Transient Search
Experiment (ROTSE) began to take images of the event. Five seconds after
they started observering it, the burst reached its peak intensity.
"If this burst had originated in the Milky Way Galaxy, it would have lit
up the night sky," said Dr. Alan Bunner, Director of NASA's Structure and
Evolution of the Universe science theme at NASA Headquarters.
Up until now, scientists had only been able to capture the afterglow of
the events and never the burst itself. Hopefully these images and others
that can be collected using similar automated detection systems will help
scientists determine what causes gamma ray bursts.
