Breakthrough Neutron-Star Collision in Tiny Galaxy Reframes GRB Origins
Astronomers detected a neutron-star collision in a tiny, faint galaxy inside a 600,000-light-year gas stream, about 4.7 billion light-years away, challenging where such events occur and linking them to gamma-ray bursts and the production of heavy elements like gold and platinum, with observations from Fermi, Chandra, Swift, and Hubble.
