| Gamma rays are the most energetic form of light we have detected. Here, the Space Place Kids see how the sky might look with the future Gamma-ray Large Area Space Telescope (GLAST). Gamma rays come from black holes, neutron stars, supernovae (stars exploding at the end of their lives), pulsars, quasars, and other sources we don't understand yet. Great bursts of gamma rays occur frequently, and it's still a mystery where they are coming from. |
