Astronomers have observed the longest-ever gamma-ray burst -- a powerful, extragalactic explosion that lasted over seven hours. Rapid follow-up observations with the U.S. Department of Energy-fabricated Dark Energy Camera and the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab, provided crucial information about the possible origin of this extraordinary event and the galaxy that hosts it.Gemini and Blanco Telescopes Unlock Clues to Origin of Longest Gamma-ray Burst Ever Observed
