The movie shows the intensity of gamma rays with energies above 200 million electron volts (MeV) detected by Fermi’s Large Area Telescope (LAT) between August 2008 and August 2022. Gamma rays are the highest-energy form of light. ![]() Our Sun, occasionally flaring into prominence, serenely traces a path through the sky against the backdrop of high-energy sources within our galaxy and beyond. The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA’s Fermi Gamma-ray Space Telescope. Watch this video on the NASA Goddard YouTube channel.
