Gamma rays are the most energetic type of light, packing a punch strong enough to pierce through metal or concrete barriers. More energetic than X-rays, they are born in the chaos of exploding stars, the annihilation of electrons and the decay of radioactive atoms.
Mission News. Not counting transient events such as gamma-ray bursts, the brightest object in the gamma-ray sky is the plane of our Milky Way Galaxy. This glow results from a vast sea of cosmic-ray particles slamming into interstellar gas and dust, generating gamma rays. In fact, 75% of the gamma rays in our galaxy come from these cosmic-ray interactions.
