NASA's Fermi Gamma-ray Space Telescope has been watching the sky for 14 years, and now researchers have created a fascinating 14-year timelapse of the high-energy sky. When you watch the video, you can see the Milky Way across the center of the screen and how the Sun makes a regular journey across the sky. The bright objects away from the Milky Way are other galaxies with active galactic nuclei. Occasionally, gamma-ray bursts flash randomly across the sky.
