"Stunning 14-Year Timelapse Captures Gamma-Ray Sky's Beauty"
NASA's Fermi Gamma-Ray Space Telescope has compiled a timelapse of its data collected between August 2008 and August 2022, revealing the sources of gamma radiation in the Universe. The timelapse showcases the Sun's steady arc across the screen, blazar galaxies with active supermassive black holes, and other sources such as supernova remnants. Fermi's observations provide insights into the most energetic events and objects in the cosmos, despite the challenges of studying gamma radiation from Earth's surface.
