TEMPO.CO, Jakarta – For scientist discover a mysterious radio signal in outer space that explodes in a heartbeat-like pattern and they state that the mysterious signal is not alien.
Use radio telescope CHIME (Canadian Hydrogen Intensity Mapping Experiment), astronomers see fast radio bursts (FRBs) from galaxies billions of light years away from Earth.
The signal lasts up to three seconds, which is very long for an FRB. “The team also detected bursts of radio waves that repeat every 0.2 seconds in a clear periodic pattern, similar to a heartbeat,” according to a press release from WITH.
“That’s unusual,” said Daniele Michilli, a postdoctoral researcher at MIT’s Kavli Institute for Astrophysics and Space Research, in a press release.
“Not only is it very long, lasting about three seconds, but there is a very precise periodic peak, emitting every split second — boom, boom, boom — like a heartbeat. This is the first time the signal itself is periodic,” he said.
But then again, it’s not the aliens that reach us. The signal, scientists say, may come from a type of neutron star.
“There aren’t many things in the universe that emit strictly periodic signals,” Michilli, part of the team that discovered FRBs, told MIT.
“Examples that we know of in our own galaxy are radio pulsars and magnetars, which rotate and produce beams similar to lighthouses. And we think this new signal could be a magnetar or a pulsar on steroids,” he said.
