Fermi Gamma-ray Space Telescope

NASA's Fermi Gamma-ray Space Telescope surveys the high-energy sky with the Large Area Telescope and Gamma-ray Burst Monitor. Together they study pulsars, gamma-ray bursts, black-hole-powered galaxies, cosmic particle acceleration, solar activity, and possible signatures of fundamental physics.

Description
NASA's Fermi Gamma-ray Space Telescope surveys the high-energy sky with the Large Area Telescope and Gamma-ray Burst Monitor. Together they study pulsars, gamma-ray bursts, black-hole-powered galaxies, cosmic particle acceleration, solar activity, and possible signatures of fundamental physics.
Launch Site
Outcome
Fermi remains active in an extended mission, scanning the full sky about every three hours. Its discoveries include hundreds of gamma-ray pulsars, the enormous Fermi Bubbles above and below the Milky Way, and high-energy counterparts associated with gravitational-wave and neutrino events.
