caption_attribution_description: English: 09/09/2011 All-sky image, constructed from two years of observations by NASA's Fermi Gamma-ray Space Telescope, shows how the sky appears at energies greater than 1 billion electron volts (1 GeV). Brighter colors indicate brighter gamma-ray sources. For comparison, the energy of visible light is between 2 and 3 electron volts. A diffuse glow fills the sky and is brightest along the plane of our galaxy (middle). Discrete gamma-ray sources include pulsars and supernova remnants within our galaxy as well as distant galaxies powered by supermassive black holes. (Credit: NASA/DOE/Fermi LAT Collaboration)
context_page_description: The CALorimetric Electron Telescope is a space telescope being mainly used to perform high precision observations of electrons and gamma rays. It tracks the trajectory of electrons, protons, nuclei, and gamma rays and measures their direction, charge and energy, which may help understand the nature of dark matter or nearby sources of high-energy particle acceleration.
  The mission was developed and sponsored by the Japan Aerospace Exploration Agency, involving teams from Japan, Italy, and the United States. CALET was launched aboard JAXA's H-II Transfer Vehicle Kounotori 5 on 19 August 2015, and was placed on the International Space Station's Japanese Kibo module.
