We've never stopped exploring space, but what would we do if we actually got a signal from an extraterrestrial civilization?

Researchers in Canada and India, with the help of a giant telescope in India,A radio signal has been captured from a galaxy called SDSSJ0826+5630, nearly 9 billion light years from Earth.It is the first time such a radio signal has been detected from such a distance.

The radio waves will allow astronomers to go back in time and learn about the early universe, the report said. Scientists believe the universe is about 13.7 billion years old. That's like looking back 8.8 billion years, said cosmologist and co-author of the study, Chakraborty.

However, The signal was not sent by aliens, but from galaxies that formed when the universe was only 4.9 billion years old.

A galaxy emits different kinds of radio signals, and until now, we've only been able to pick up this particular signal from nearby galaxies, limiting our knowledge to those closer to Earth, Chakraborty said.

Some netizens were caught up in the imagination and even recalled Hawking's famous "don't answer."
