Astronomers have captured the most distant fast radio burst ever recorded. The millisecond burst of radio energy traveled about 10 billion years through space to reach Earth. NASA's James Webb Space Telescope confirmed the distance and then traced the signal back to a small, young galaxy.

The find provides astronomers a clearer picture of where these high-energy pulses come from. Fast radio bursts have stumped astronomers for years. This one breaks the previous distance record and suggests a likely origin for the entire phenomenon.
