On Aug 4, 2017, Fermi detected a powerful, short gamma-ray burst located 130 million light-years away. Those gamma rays had friends! @NSF’s LIGO also detected gravitational waves from this pair of colliding neutron stars. go.nasa.gov/31lcAzw
Almost every day Fermi detects gamma-ray bursts lasting from a fraction of a second to over 1,000 seconds. Many of these events signal the birth of a black hole. nasa.tumblr.com/post/176492220…
A neutrino that had traveled 3.7 billion years was detected by @uw_icecube, and Fermi helped trace the source of this hard-to-catch particle to a flaring blazar — a type of galaxy powered by a supermassive black hole. go.nasa.gov/2XsneU4
Thunderstorms happen tens of thousands of times a day, and sometimes they fire off short bursts of the highest-energy light! Fermi has seen more than 4,000 of these terrestrial gamma-ray flashes, and each detection helps us better understand these events. nasa.tumblr.com/post/172592332…
Correction: The gamma-ray burst happened on Aug 17, 2017
