Astronomers

Using NASA’s Chandra X-ray Observatory and other telescopes, astronomers have traced a short-duration gamma-ray burst event called GRB 230906A to a faint dwarf galaxy embedded in a vast stream of intergalactic gas. This discovery suggests that some neutron-star mergers — violent collisions that forge heavy elements like gold and platinum — can occur far from
