Gamma Ray Bursts and Black Holes

GRB

On February 2 NASA’s satellite, Swift, was hit by cosmic gamma rays. This triggered an alert and seconds later University of WA’s Zadko Telescope swung into robotic action to take images and record the entire evolution of the event. The event appeared as a rapid brightening visible in the sky for a brief period of time. Its brightness was equivalent to millions of stars shining together from the same location. What was actually detected is known as a Gamma Ray Burst.
