A radio signal from 8 billion light-years away may reveal the secrets of the ‘dark age’ of the universe

Using warped space-time as a magnifying glass, astronomers have captured the most distant signal from a distant galaxy, and it could open a window into how our universe formed.

The record-breaking radio frequency signal, picked up by the Giant Metrewave Radio Telescope (GMRT) in India, came from the galaxy SDSSJ0826+5630, located 8.8 billion light-years from Earth, which means the signal went off when the universe was roughly a third of its current age. .
