Intense flash of radio waves is more than 10bn years old and has travelled through ‘approximately 80% of cosmic history’

Astronomers have now detected that flash, a burst of radio waves which travelled for more than 10bn years before reaching Earth – what they believe to be the most distant fast radio burst (FRB) ever recorded.
