Fermi Gamma-ray Space Telescope

Fermi Fridays - September

Find out about how Fermi has improved our understanding of how the Sun can accelerate particles, producing bright and long-lived gamma-ray emission.
Fermi's Large Area Telescope (LAT) observes continuous emission of gamma rays from two of our closest and most familiar celestial objects. Find out more about what causes this high-energy glow.
Most of what the Fermi Gamma-ray Burst Monitor (GBM) sees comes from the Sun.
Inspired by solar flares, Animation students put them into a more human context.
