For the first time, scientists have used the James Webb Space Telescope (JWST) to study the origins of a bizarre, record-breaking radio signal that flashed past Earth earlier this year.
Tracking the bright radio burst to the edge of a galaxy some 130 million light-years from Earth, the researchers used JWST's infrared eye to identify a powerful explosion of energy coming from a large, old star that may be the strange signal's progenitor. The team also zoomed in on specific stars clustered nearby, painting a picture of the radio burst's original environment with unprecedented clarity.
