An intense and brief radio signal from the Milky Way was recorded last week by astronomers. It would be a “rapid radio burst”, making it the first detected in our galaxy.
Radio telescope sensors detected it on Tuesday, April 28, coming from a magnetar (or magneto star), a neutron star with a strong magnetic field, resulting from the transformation of a supernova. The one in question, named SGR 1935 + 2154, is 30,000 light years from Earth, reports Futura-sciences. Either in our Milky Way.

The brevity of the emission (one millisecond) and its power (scientists believe that the signal could very well have been observed from another galaxy) makes astronomers say that it could be a “rapid radio burst” . The phenomenon, already identified in the universe, but not in our galaxy, is at the heart of many hypotheses to explain it: collision of magnetars, supernovas, even even extraterrestrial civilization.
To validate the idea that magnetars are the source of rapid radio bursts, astronomers will analyze SGR 1935 + 2154 emissions when the signal is received. A coincidence would comfort them in their search. But neither would it rule out that other sources could also be at the origin of it.
