NASA | NASA's Fermi Shows How Active Galaxies Can Be
Loading...
Uploaded by NASAexplorer on Sep 8, 2011
Active galaxies called blazars make up the largest class of objects detected by Fermi's Large Area Telescope (LAT).

Fermi team member Elizabeth Hays narrates this quick tour of blazars, which includes LAT movies showing how rapidly their emissions can change.
