Scientists find four mysterious circular objects in space via radio telescope

New Delhi : Finding new things in space is a distinct nature of astronomers and this time they have spotted four mysterious circular objects with the help of a radio telescope called the Australian Square Kilometre Array Pathfinder, reported The Independent.

Three out of four spotted circular objects have clear edges and the researchers are still clueless over the fact how they must have formed.

The findings of the researchers have been published on arXiv and it has been submitted for publication in Nature Astronomy.

According to the scientists, it has been speculated that they must have been formed due to a spherical shock wave generated from the blast from powerful events such as fast radio bursts, gamma-ray bursts or neutron star mergers.

They say that the objects could be the result of looking at the jets of a radio galaxy down the end or might be a variety of different things, which have been spotted at the same time because of new observational capabilities.

"[The objects] may well point to a new phenomenon that we haven't really probed yet. It may also be that these are an extension of a previously known class of objects that we haven't been able to explore," Live Science quoted Kristine Spekkens, an astronomer at the Royal Military College of Canada and Queen's University, as saying. Spekkens was not involved with the new study.

The mysterious objects were spotted during the mapping of night sky in radio frequency. The mapping was done as a part of a pilot survey for a new project called the Evolutionary Map of the Universe (EMU).
