Scientists Detected Mysterious Radio Signal Coming From Our Galaxy:- FRB

Scientists have detected mysterious and powerful radio signals coming from within our own galaxy.

Fast radio bursts (FRBs) are a puzzling phenomenon first detected in 2007-but they have never been identified by previous observations from within our own galaxy.

Fast radio bursts, or FRBs, last only a fraction of a second, but maybe 100 million times more powerful than the Sun. Despite their intensity, their origins remain largely unknown.

In about 1 millisecond, the magnetar emitted as much energy in radio waves as the sun emits in 30 seconds.

Now, for the first time ever, astronomers have been able to observe a Fast radio burst (FRBs) in our own galaxy. And this could help to solve the mystery of where they came from.

The research is described in three research papers published in the journal Nature, based on observations made worldwide – in Canada, the United States, China, and even from space – have potentially uncovered the source.

Earlier this year, on 27 April, two space telescopes picked up powerful x-rays and gamma rays coming from the cosmic body on the other side of the galaxy. The next day when astronomers used two North American telescopes to observe that that region, they saw an enormously powerful and fast radio burst, which they named FRB 200428.

As FRBs, are so short, unpredictable, and originate far away, scientists have had trouble tracking the origin of such blasts. But this time FRB came from within our own galaxy, astronomers were able to trace it to its probable source-a type of neutron star that has a strong magnetic field called a magnetar.

What is magnetar? A magnetar is a type of neutron star that is believed to have an extremely powerful magnetic field. Magnetic field decay powers the emission of high-energy electromagnetic radiation, in particular x-rays and gamma rays. The magnetar's field strength is 1,000 trillion times stronger than Earth's and is so intense that it heats the surface to 18 million degrees Fahrenheit.

Kiyoshi Masui, assistant professor of physics at MIT, who led the team's analysis of the FRB's brightness, said, "There's this great mystery as to what would produce these great outbursts of energy, which until now we’ve seen coming from halfway across the universe," and "This is the first time we’ve been able to tie one of these exotic fast radio bursts to a single astrophysical object."

Even if it can be proven that the FRBs came from a magnetar, there are still many mysteries that remain to be clear.
