Gamma-Ray Earth
This pixelated image shows our planet Earth as seen in gamma rays, the most energetic form of light. The Earth's gamma-ray glow is very faint, requiring seven years of data from the Compton Gamma Ray Observatory. Each gamma-ray photon packs over 35 million electron volts. This unique perspective reveals Earth's interaction with high-energy cosmic radiation.
