{"Image DocumentName": "We can detect gamma rays and cosmic rays emitted when huge stars go supernova and create black holes", "Image ImageDescription": "Cosmic \uf067-rays must be observed from above our atmosphere. since the 1960s, satellites have detected strong bursts of \uf067-rays. they occur daily, for a few minutes. \uf067-rays are hard to focus, so determining their direction is tough. We call these monsters Gamma Ray Bursters. we can pinpoint their sources to distant galaxies. What they are is still a mystery. best theory: they are hypernovae \u2026 gigantic supernovae which form black holes. most luminous events since the Big Bang.
