A Canadian radio telescope, nicknamed CHIME, has picked up a mysterious radio signal from a distant galaxy.
Signal close to the pulse: “Boom, boom”
In an article in the scientific journal temper natureOn December 21, 2019, a group of astronomers reported the interception of CHIME for mysterious radio signal It comes from a galaxy far away. According to scientists, this galactic sound, coming from the farthest reaches of space, is like a heartbeat.
The radio telescope picks up fast radio bursts (or fast radio bursts, FRBs), the first recordings of which were discovered in 2017. Since then astronauts have recorded hundreds of these fast radio bursts, which lasted for a few milliseconds before fading out, from various points in the universe.
It is difficult to determine the exact origin of the atypical signal
But on December 21, 2019, . was released fast radio blasts It lasted longer than a few thousandths of a second, and lasted up to three seconds. Reports indicate that the atypical FRB signal had a duration of about 1,000 times longer than typical FRBs 20 minutes.
This is the first time that the signal itself is periodic. The exact origin of this Signal Unknown, it likely comes from a galaxy located a billion light-years away.
