Further study of bright gamma-ray burst GRB 230307A shows it was caused by neutron stars merging

An international team of astronomers and astrophysicists has found evidence that the bright gamma-ray burst GRB 230307A observed last year was caused by two neutron stars merging, not from a collapsing massive star. In their study, published in the journal Nature, the group analyzed data from both the Hubble Space Telescope and the James Webb Space Telescope.
