(ORDO NEWS) — Earlier this year, scientists caught a radio signal from a small, dead star in the Milky Way galaxy. As it became known, the body does not stop sending signals to Earth.
Magnetar SGR 1935 + 2154 once again announced its presence, giving scientists another chance to study the space mystery. The CHIME / FRB collaboration recorded the radio signal on October 8. There were three bursts of three milliseconds in total.
Astronomer Deborah Goode from the Canadian University of British Columbia noted that experts were delighted with the next event. A careful study of the phenomena will help clarify the relationship between magnetars and fast radio bursts.
At the moment, scientists are analyzing the recorded signals. Previously, they only came from outside the galaxy. Now, the bursts are sent to some extent by close objects. For the first time they started talking about signals in 2007. Surprisingly, there is still no clear idea of their origin. Astronomers are struggling to figure out the circumstances that are causing them.
A fast radio burst is a phenomenon when powerful radio waves are generated. Some stars shed more energy than millions of suns. The duration of each signal does not exceed a few milliseconds.
It is somehow impossible to predict signals, since they appear once and practically do not repeat. In addition, they appear so far away that telescopes are unable to recognize individual stars.
As for SGR 1935 + 2154, the magnetar is 30 thousand light years from us. The previous signal was received on April 28 this year.
