The Hubble Space Telescope captured this image of a gammaray explosion on January 23, 1999. At the time it was the most powerful explosion ever recorded.
Images captured by NASA's Swift satellite show two views of the unusual gamma-ray burst, an outpouring of high-energy radiation and particles thought to follow the collapse of a massive star.
