Light is energy that can take on many forms. Radio waves, microwaves, infrared, visible, ultraviolet, X-ray and gamma radiation are all different forms of light. (Illustration: NASA/CXC/M.Weiss)

This radio, optical and gamma-ray composite illustrates the full extent of Cen A's vast radio-emitting lobes. Radio data (orange) reveal that the structures span more than 1.4 million light-years, and Fermi's LAT data (purple) show that they also emit gamma rays.<br />

Gamma-ray Bursts are flashes of gamma rays associated with extremely energetic explosions that have been observed in distant galaxies. They are the brightest electromagnetic events known to occur in the universe. Bursts can last from ten milliseconds to several minutes. The initial burst is usually followed by a longer-lived "afterglow" emitted at longer wavelengths (X-ray, ultraviolet, optical, infrared, microwave and radio).
