This stunning visual masterpiece offers us a unique glimpse into the dynamic and vibrant universe that surrounds us.

Exploring the World of Gamma Rays

Gamma rays are the most energetic form of light, far surpassing the intensity of visible light. They are produced by various astrophysical processes, including supernova explosions, pulsars, and the powerful jets emanating from supermassive black holes. These gamma-ray sources, scattered across the cosmos, hold valuable insights into the nature of our universe.

The Fermi Gamma-ray Space Telescope

The Fermi Gamma-ray Space Telescope, named after the renowned physicist Enrico Fermi, was launched by NASA in 2008 with the primary goal of studying gamma-ray emissions. Equipped with the Large Area Telescope (LAT), Fermi has been tirelessly scanning the sky, collecting data and unraveling the mysteries of…
