    "description": "Gamma rays are the most powerful form of light in the universe. In the darkness of space, these luminous rays, which are invisible to humans but detectable by spacecraft, act as celestial beacons that alert us to some of the most extreme events and objects in the cosmos. For instance, when dying stars explode as supernovae, they emit gamma rays; so do particles being sucked into supermassive black holes; as do pulsars, the rapidly rotating stars that are as massive as our sun but only about the size of Manhattan. Since 2008, NASA’s Fermi spacecraft has observed gamma rays in the Milky Way and beyond. Plotted on a map, the locations of different sources appear as bright spots in the night sky. Watch the video to see how the spacecraft detects gamma rays. || ",

Astronomers think most occur when the core of a massive star runs out of nuclear fuel, collapses under its own weight, and forms a black hole. The black hole then drives jets of particles that drill all the way through the collapsing star at nearly the speed of light. Artist's rendering.Credit: NASA's Goddard Space Flight Center ",

(For comparison, the energy of visible light is between 2 and 3 electron volts.) The image contains 60 months of data from Fermi's Large Area Telescope; for better angular resolution, the map shows only gamma rays converted at the front of the instrument's tracker. Brighter colors indicate brighter gamma-ray sources. The map is shown in galactic coordinates, which places the midplane of our galaxy along the center. The five-year Fermi map is available in multiple resolutions below, along with additional plots containing reference information and identifying some of the brightest sources. || ",
