Astronomers have found a collision between neutron stars within colliding galaxies, which are thought to be the only events in the universe capable of generating heavy elements like gold and silver. The powerful blast of radiation, known as a gamma-ray burst (GRB), was tracked back to its source using NASA space telescopes including the Chandra X-ray Observatory, the Fermi Gamma-ray Space Telescope, the Neil Gehrels Swift Observatory, and the Hubble Space Telescope. The discovery could reveal more about these collisions, which were previously observed in medium to large galaxies. The home galaxy of this merger is thought to have been created when a group of galaxies collided hundreds of millions of years ago.
