In an incredible discovery, scientists have detected a radio signal from a galaxy more than 9 billion light-years away from Earth. This is the most distant radio signal ever detected and has been hailed as a major breakthrough in the study of the universe.

The signal was detected by the Giant Metrewave Radio Telescope in India and was sent from a galaxy known as J0842+1835. Scientists believe the signal was generated by an atomic hydrogen emission line, which is a type of radiation emitted from hydrogen atoms.

The signal is believed to be a remnant of the early universe, which is estimated to be around 13.8 billion years old. This means the signal was sent from a time when the universe was only 4.2 billion years old.

The signal has provided scientists with a unique insight into the history of the universe, unlocking secrets that had previously been hidden.

The discovery has been hailed as a major breakthrough, with scientists saying it could help us better understand the formation and evolution of galaxies and the universe.

The signal was also detected by other telescopes around the world, including the Very Large Array in New Mexico and the Australia Telescope Compact Array.

This discovery is a major step forward in our understanding of the universe and will help us unlock its secrets.
