An unusual explosion of radio waves was detected in a distant galaxy.  Astronomers now have a new mystery to solve

Astronomers have detected an explosion where from mysterious radio, which repeats itself, coming from a dwarf galaxy 3 billion light-years away, CNN reports.

These radio waves are different from those detected in recent years, according to new research. Radio waves, or FRB, are millisecond radio waves detected in space. They usually occur only once few it’s repeating.

Astronomers have been able to track down some explosions where from radio to their galaxies originatingbut have not yet determined the true cause of their. Scientists are trying to afle more about the origin of these radio emissionsa intense to I seee what causes them.

Astronomers have detected the cosmic object called FRB 190520 when he launched a radio explosion on May 20, 2019. Researchers used the FAST radio telescope ofin China and they discovered a new explosivese in datacollected them in November 2019. When they made further observations, astronomers noticed something unusual – the object emitted frequent and repeated bursts of radio waves.

In 2020, the team used VLA telescopes from the National Science Foundation, and the telescope Subaru from Hawaii to study these FRB and found that the explosion is comingshe from the periphery of a distant dwarf galaxy.

A study detailing the findings research was published Wednesday in the journal Nature.

VLA’s observations also showed that the object cosmic constantly released where weaker radio between repeated emissions of FRB. This isis very similar to another FRB repeatitive: FRB 121102, discovered in 2016.

“Now we have to explain this double mystery and why persistent FRBs and radio sources appear sometimes together, “said Casey Law, co-author ofl study and researcher at the California Institute of Technology. “It is one thing usual when these cosmic objects are young? Or maybe the object that produces the explosions is a massive black hole that swallow slowly a neighboring star?sof questioned he.

The researchers noted that less than 5% of the hundreds of FRB identified are repeated and only a few of them are active on a regular basis.

But FRB 190520 is the only persistent asset, which means it is not stopped at all since it was discovered, said Di Li, the study’s author and head of the radio division of the National Astronomical Observatories of China and the FAST Operations Center.

In the change FRB 121102 may not emit months completesaid Li.

The latest findings raise many questions, as astronomers are now wondering if there could be two types of FRB.

“It simply came to our notice thenyourself by those who do not repeat themselves? What about persistent radio broadcasting – is it commonplace? ” he wonders co-author of the study Kshitij Aggarwal, PhD student at West Virginia University.

There may be different mechanisms that cause radio explosions or as their source to behave differently at different stages of evolution.

Scientists have previously hypothesized that fast radio explosions are caused by dense debris left behind by a supernova called a neutron star, or stars with incredibly strong magnetic fields called magnets.and.

FRB 190520 is considered a possible “newborn” object because is in a dense environment, Law said. This environment can be caused by the material released by a supernova, which led to the creation of a neutron star. As this material spreads, the explosions at FRB 190520 would putshe it was decreasing.
