James Webb Space Telescope detects violent collision between neutron stars

Using the James Webb Space Telescope (JWST), astronomers have traced an extremely bright gamma-ray burst (GRB) to its origin, a violent collision between two neutron stars.

The ring on your finger likely contains atoms produced in neutron star collisions like this, also known as «kilonova». That’s because, as well as blowing up the GRB over long periods of time, the kilonova is thought to be the forge of the universe’s heaviest elements, which cannot be synthesized in the nuclear furnaces at the heart of stars.
