NASA's Fermi Explores High-energy "Space Invaders"
January 10, 2013
The Large Area Telescope (LAT) on Fermi detects gamma-rays by tracking the electrons positrons they produce after striking layers of tungsten. This ability also makes the LAT an excellent tool for exploring high-energy cosmic rays. Credit: NASA/Goddard Space Flight Center Conceptual Image Lab
