Multiple telescopes observed a rare cosmic explosion called a kilonova that created heavy elements in space, including some necessary for life.

The James Webb Space Telescope and other observatories witnessed a massive explosion in space that created rare chemical elements, some of which are necessary for life. The explosion, which occurred on March 7, was the second brightest gamma-ray burst ever witnessed by telescopes in more than 50 years of observations, over one million times brighter than the entire Milky Way Galaxy combined. Gamma-ray bursts are short emissions of the most energetic form of light.

But it seems to be coming from a merging neutron star,” said study coauthor Eric Burns, assistant professor of physics and astronomy at Louisiana State University, in a statement. Fermi initially detected the gamma-ray burst, and astronomers used ground- and space-based observatories to track the changes in brightness during the aftermath of the explosion in gamma-ray, X-ray, visible, infrared and radio waves of light. The quick changes in visible and infrared light suggested it was a kilonova.
