Astronomers have detected a Fast Radio Burst (FRB) that lasts 1,000 times longer than other similar cosmic signals.. According to scientists, it may come from a neutron star " com.

Most FRBs, which are powerful bursts of radio waves from galaxies billions of light years away, last for milliseconds and then disappear.. They are often single events..

The new signal, FRB 20191221A, lasts three seconds, which is 1000 times longer than other similar radio bursts.. In addition, it has the clearest repeating structure of all such signals known so far..

According to Daniele Michilli of the Institute of Astrophysics and Space Research.. Kavli of the Massachusetts Institute of Technology, the signal had periodic peaks that sounded very clear, repeating every fraction of a second, and looked like a heartbeat.

In the future, scientists hope to capture other repeated bursts from this source, which will help to more accurately determine its nature.. In addition, they hope that FRB 20191221A can be used as a type of " Since the frequency of this burst will change as the source moves away from the Earth, these changes can be used to measure the expansion of the universe..

Since the discovery of the first FRBs in 2007, scientists have been trying to find out what is their source.. So far, the most likely candidate sources are the types of neutron stars called radio pulsars and magnetars.. A new study may confirm this theory is correct, as few objects in the universe are known to emit clearly periodic signals..

Earlier, scientists from the National Astronomical Observatory of the Chinese Academy of Sciences, using the world's largest radio telescope FAST, discovered three fast radio bursts. These radio bursts happened billions of years ago, when the universe was young, the researchers say..
