In a celestial dance of gamma rays, NASA’s Fermi Gamma-ray Space Telescope has compiled a breathtaking 14-year time-lapse tour of the universe's high-energy panorama. 

Compressing over a decade of observations into a six-minute visual odyssey, this video unveils the pulsating heart of our Milky Way, punctuated by explosive flares from distant galaxies harboring voracious black holes.

The cosmic cinema, unveiled by the Fermi team, showcases gamma-ray intensity above 200 million electron volts—a stark contrast to the mere two to three electron volts of visible light—captured by the Large Area Telescope (LAT) from August 2008 to August 2022. Viewers are treated to a luminous ballet of gamma-ray sources, each flare and flicker narrating the violent processes shaping our universe.

Amid this high-energy spectacle, our Sun makes occasional dramatic appearances, its path tracing the orbital journey of Earth, casting new light on the familiar star against a backdrop of far more distant and energetic phenomena.

These captivating sequences spotlight eruptions from supermassive black holes residing in the cores of remote galaxies. As these cosmic giants feed, they eject near-light-speed jets, resulting in the intense flares captured in the time-lapse, offering a glimpse into the tumultuous and energetic universe beyond our immediate celestial neighborhood.

Narrated by Judy Racusin, Fermi’s deputy project scientist, the video doesn’t just chronicle the universe’s highly-charged drama; it also guides viewers through the cosmic phenomena, providing valuable insights into the gamma-ray sky.
