September 10, 2008--A recent big bang--which was aimed directly at Earth--lights up the skies in an artist's conception.

A powerful stellar explosion on March 19 created a massive gamma ray burst seen worldwide by satellites, observatories, and the naked eye.

The unusual blast propelled material from a doomed star in the constellation Bovtes directly toward our planet in a two-component jet represented by white and green beams.
