Mysterious radio waves reach Earth from unknown direction – “We have never seen anything like this”

Unusually radio waves coming from its center galaxy we were spotted by an international team of astronomers. In fact, these waves do not match any known radio source, so they probably come from some hitherto unknown object space. No scientist, at present, has a clear answer as to their origin.

More specifically, researchers from various countries (Australia, USA, Canada, Spain, France, South Africa) who made the relevant publication in the Astrophysical Journal, stated that “the strangest property of the new brand is that it has very high polarization, which means that its light oscillates only in one direction, but this direction rotates over time “.

They also pointed out that the brightness of the object fluctuates dramatically, by 100 times, and the signal seems to “flash” randomly. We have never seen anything like itSaid researcher Zitteng Wang of the Institute of Astronomy and the School of Physics at the University of Sydney.

“The behavior was completely unusual”

“Looking at the center of our galaxy, we found this object that is unique, as at first it was invisible, then it became bright, then it faded and then it reappeared. The behavior was completely unusualSaid Professor Tara Murphy, also of the University of Sydney.

According to the APE-MPE, many species of stars emit variable light in the electromagnetic spectrum. Neutron stars (pulsars), supernovae (supernovae), stars that send flashes in space, and fast radio waves (FRBs) are such astronomical objects whose brightness fluctuates.

But the new source, originally discovered by the Australian radio telescope ASKAP and confirmed to exist by the South African radio telescope MeerKAT, does not seem to match any of these phenomena. Having detected six radio signals with ASKAP over nine months in 2020, astronomers then tried to observe it with an optical telescope, but failed. The attempt of the Parkes radio telescope was just as unsuccessful, but finally the most sensitive MeerKAT rediscovered this year the mysterious object, which was christened “Andy’s object” (after the nickname of the astronomer who first discovered it).

What we know about the new unknown source

The Earth from space

As Murphy said, “We were lucky that the signal returned, but we found that his behavior was dramatically different. The source disappeared in just one day, although it had lasted for weeks, when we had observed it with the ASKAP radio telescope “.

The new unknown source is probably small in size and has a strong magnetic field, is added to other mysterious radio objects that have been discovered relatively recently near the galactic center and also have varying brightness (hence the name “Galactic Center Radio Transients”). Within the next decade, the large Internet-connected intercontinental radio telescope SKA (Square Kilometer Array) will be put into operation, which hopes to shed more light on these mysterious objects.
