Narrated Tour of Fermis 14 Year Gamma Ray Time Lapse

The cosmos comes alive in an allsky timelapse movie made from 14 years of data acquired by NASAs Fermi Gammaray Space Telescope. Our Sun, occasionally flaring into prominence, serenely traces a path though the sky against the backdrop of highenergy sources within our galaxy and beyond. Gamma rays are the highestenergy form of light. The movie shows the intensity of gamma rays with energies above 200 million electron volts (MeV) detected by Fermis Large Area Telescope (LAT) between August 2008 and August 2022. For comparison, visible light has energies between 2 and 3 electron volts. Brighter colors mark the locations of more intense gammaray sources. The movie shows the sky in two different views. The rectangular view shows the entire sky with the center of our galaxy in the middle. This highlights the central plane of the Milky Way, which glows in gamma rays produced from cosmic rays striking interstellar gas and starlight. Its also flecked with many other sources, including neutron st
