Scientists are getting strange signals from the galaxy located 3 trillion light years away!

A fast radio burst (FRB) emanating from a galaxy located 3 trillion light years away has baffled astronomers. These are bursts of radio waves that are as long as milliseconds. These radio bursts are born but do not repeat. However, the latest observations have found repeating radio bursts. Astronomers detected an object named FRB 190520 on 20 May 2019.

Its location was detected by the Five Hundred Meter Aperture Spherical Radio Telescope (FAST) in China. After that this radio burst appeared in the telescope data in November. On further study of FRB 190520, scientists found that it is a burst of rapidly repeating radio waves. This study has been published under a new report in the journal Nature.

In 2020, the team of scientists used the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) and other telescopes and located it. After locating, Hawaii’s Subaru Telescope presented a more clear picture of it. Visible light observations from the Subaru Telescope revealed that the burst came from a small galaxy that is 3 trillion light-years away. It was also noted that the object gave off persistent but weak radio waves.

According to Casey Law, a staff scientist at the California Institute of Technology and co-author of the study, the first FRBs that VLAs located in 2016 have similar properties to the same FRBs. The FRB 121102 found in 2016 also produced more frequent bursts, as did FRB 190520. Now we have two such bursts, and they both raise some very important questions. Astronomers think that there are two types of fast radio bursts. They say that by studying FRB 190520, the earth and the material present between them can be detected.
