Are aliens trying to contact the Earth? Six new mysterious blasts of radio energy are detected from deep space. While the source of the waves remains unknown, some suggest the mysterious bursts of energy could be a sign of alien life trying to contact us. The waves were detected by researchers from McGill University in Montreal.

The detection follows 11 previously recorded fast radio bursts (FRBs) from the same location, called FRB121102. This is the only known repeater of FRBs. Although there have been a number of FRBs from the site, the origin of the radio bursts remains a puzzle to researchers.

But the researchers say that the repeated FRBs imply that whatever is causing the FRBs is not a one-time event, such as an explosion or a collision. Instead, they say that flares (耀斑) from a young neutron star (中子星) are a promising candidate.

Previously when waves have been detected, astronomers have also asked Search for Extraterrestrial Intelligence (SETI) to take a closer look at whether they could be a message from aliens. But it is unclear whether the researchers will ask SETI to help this time.

If there were any intelligent alien life forms out there, in Stephen Hawking’s opinion, we were playing a dangerous game by trying to contact them. If alien s discovered the Earth, they would likely want to conquer and colonize our planet.

But the co-founder and former director of the SETI Institute, Jill Tarter, doesn’t think this will be the case. She argues any alien s who have managed to travel across the universe may be friendly and peaceful. “The idea of a civilization which has managed to survive far longer than we have... and the fact that the technology remains an aggressive one, to me, doesn’t make sense,” she said.
