Eine Testzündung der Triebwerke erfolgte am 28. This allows for uniform and long-term monitoring of blazars, which are AGNs that were found to dominate the gamma-ray sky by the Compton Gamma Ray Observatory, the forerunner to Fermi. When one of these poles points at Earth, we pick up gamma rays. Such an increase in sensitivity can only … 1999), and Fermi found 1451 sources during the first 11 months of the all-sky survey (Abdo et al. With the capabilities the Space Shuttle provides, scientist now have the means for deploying these observatories from the Shuttle’s cargo bay directly into orbit. 1991.It took its name from the 20th-century US physicist Arthur Holly Compton. The current theory is that gamma ray bursts are generated when protogalaxies collapse into supermassive black holes, the galaxy's material releasing its gravitational potential energy as electromagnetic radiation. What is the United States National Radio Quiet Zone. This mission collected data on some of the most violent physical processes in the Universe, characterized by their extremely high energies.
