NASA telescopes have detected the brightest, most high-energy flood of radiation from space ever recorded.

About 1.9 billion years ago, a dying star collapsed, exploding in a powerful burst of gamma rays that careened toward Earth. Finally, they washed over our planet on October 9. They set off detectors on three telescopes in orbit: the Fermi Gamma-ray Space Telescope, the Neil Gehrels Swift Observatory, and the Wind spacecraft.

Those telescopes, and other observatories around the world, quickly homed in on the source of the radiation: a distant object now called GRB 221009A, pulsing with the powerful glow of its gamma-ray emissions.

It was the most luminous, powerful event ever detected, NASA announced on Thursday. The telescopes’ images show just how dramatic the explosion was.
