Fermi’s latest gamma-ray census highlights cosmic mysteries

Every three hours, NASA’s Fermi Gamma-ray Space Telescope scans the entire sky and deepens its portrait of the high-energy universe. Every year, the satellite’s scientists reanalyze all of the data it has collected, exploiting updated analysis methods to tease out new sources. These relatively steady sources are in addition to the numerous transient events Fermi detects, such as gamma-ray bursts in the distant universe and flares from the sun. Earlier this year, the Fermi team released its second catalog of sources detected by the satellite’s Large Area Telescope, producing an inventory of 1,873 objects shining with the highest-energy form of
