Brightest light from black hole's spit

摘要

Globs of plasma spat out by black holes can trigger the brightest flashes of light in the universe. Gamma-ray bursts are high-energy flares that mostly originate billions of light years away, making it hard to see how they are created. In November 2011, NASA's Fermi satellite saw a gamma-ray burst coming from the galaxy 4C +71.07, which sits about 10.5 billion light years away.
