Explore the Universe with the First E-Book from NASA’s Fermi

Fermi provides a unique view of the universe and allows us to study some of its most curious phenomena. Fermi’s position in low-Earth orbit enables it to detect thousands of gamma-ray sources and reveal new high-energy discoveries. Fermi is the first imaging gamma-ray telescope to survey the entire sky each day, with one full survey taking only three hours.

Importantly, Fermi does not work alone; some of its important discoveries have also relied on observations from the likes of NASA’s Neil Gehrels Swift Observatory, Hubble Space Telescope, and James Webb Space Telescope.
