ASKAP (Australian Square Kilometer Array Pathfinder), a sensitive space telescope of Australia, detects a mysterious repeating radio signal in the Milky Way Galaxy's center. Involved astronomers said that they were able to receive this unknown radio wave around 13 times between April 2019 and August 2020.
However, they were not able to detect it again, which prevented them from further observing the radio signal to know its origin and existence. Because of this, space experts are now confused about the actual source of the radio signal.
NASA explained that radio signals usually come from astronomical objects, which have to change magnetic fields that produce radio waves. The National Aeronautics and Space Administration's WAVES, a radio astronomy instrument, usually detects radio signals coming from the Sun and other planets within the solar system.
Aside from stars and other heavenly bodies, space experts also explained that nebulas, quasars, and pulsars are also among the most common sources of radio signals. However, the latest mysterious repeating radio signal seems to be not coming from them.
Why ASKAP Radio Signal Confuses Astronomers
According to Slash Gear's latest report, the involved Australian space researchers said that the mysterious repeating radio signal they detected is not a pulsar, a low-mass star, or even a fast radio burst.
Aside from its unknown origin or form, ASKAP astronomers also confirmed that the repeating radio signal, which is now called ASKAP J173608.2-321635, will appear very bright in the radio system for weeks. After that, it would suddenly disappear within around 24 hours.
On the other hand, the Australian experts added that the behavior of the new radio wave also doesn't fit any recorded celestial body types.
Since this is the case, they believe that this signal could represent a new class of space objects, which could be discovered via radio imaging.
Other Details of the Repeating Radio Wave
Express UK reported that the new study, which Ziteng Wang leads, states that the repeating radio signal could be a highly polarized, variable radio source.
On the other hand, the involved University of Sydney researchers explained that there's a high possibility it came from the center of the Milky Way Galaxy, which is still an unexplored area.
Aside from these, astronomers also said that it does not appear when they are using other types of space telescopes, such as the Chandra X-ray Observatory and the Swift Observatory, which can pick up near-infrared wavelengths.
