Astronomers have detected 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 measured the distance and traced the signal back to a small, young galaxy.

The find offers scientists a clearer picture of where these high-energy pulses come from. Fast radio bursts have puzzled scientists for years. This one sets a new distance record and points toward a likely origin for the whole class of events.
