A Radio Signal Repeating Like a Heartbeat in Space

The work of astronomers to explore space is just James Webb Space Telescope It does not focus on our visual perceptions such as Radio signals and different data are also among the topics that researchers focus on.

Among these studies from deep space A radio signal has caught their attention. Because this radio signal can be observed with a certain rhythm and a certain strength, like the regular beating of a heart. Scientists, on the other hand, make an assumption about the source of this signal.

Signal can be detected regularly

According to astronomers, the source of these signals that come regularly is the remains of a long-dead star. Pulsar or magnetar The general name of these structures, which are called neutron stars. These structures, which have very high speed and very high density value, are on the verge of becoming a black hole. From time to time, they also emit radio signals into space. These signals also fast radio bursts is named.

Although this phenomenon has been known for a very long time, the reason why new radio waves have attracted so much attention duration and rhythm it happened. A very periodic repeating signal every 0.2 seconds reverberated through space for about three seconds. This period is about 1000 times longer than a normal burst of fast radio waves.

Work in this area has also intensified since the first fast radio burst was discovered in 2007. scientists now FRB 20191221A they have even more carefully scrutinized the source from which this fast radio wave came from. The aforementioned radio burst has also been detected by MIT and many other research institutions.

Discovery review on 13 July 2022 nature was published in the magazine.
