What is the unidentified 'ORC' floating in the universe where experts are excited that 'the current theory cannot explain'?
There are still many mysteries left in the universe, one of which is the ' ORC ', a 'ghostly strange circle' floating in the night sky that can only be observed with a special radio telescope. Ray Norris, a professor of science at the University of West Sydney and the

'WTF?': Newly discovered ghostly circles in the sky can't be explained by current theories, and astronomers are excited

In 2019, astronomer Anna Kapinska noticed a strange object that did not match existing data while browsing radio astronomy data. The object labeled 'WTF' (what is this) by Mr. Kapinska is a circle consisting of radio wave radiation, and it is said that it was floating in space in a vague state like smoke. A few days later, Kapinska's colleague Emil Lenz discovered a similar substance.
Kapinska and Lenz then continued their research as part of an EMU project to investigate radio sources in space using the Australian Federal Institute for Scientific and Industrial Research (CSIRO) ASKAP telescope. EMU is a project proposed by Norris in 2009 to investigate the universe on a large scale with the ASKAP telescope, which could not be captured by existing telescopes. From the beginning of EMU, it was thought that 'you will find something that researchers do not anticipate,' but 'I didn't expect to find something that was beyond our expectations so quickly. 'Norris said.
EMU investigations have since discovered several similar objects. The series of objects that Mr. Kapinska read as 'WTF' was named 'Odd Radio Circles (ORC)' by EMU.
It was suspected that the ORC was an artificial image generated by a software error, but by proceeding with the investigation using other radio telescopes, it became clear that it was an 'actual object'. is. It is believed that 'ORC is probably formed by a cloud of radio waves' because nothing is seen when the position of the ORC is photographed with an optical telescope. However, the location of the ORC is not yet clear as 'a few light-years to a few million light-years from Earth,' and Norris says he has no idea what it is as of 2020. Said.
While nothing specific about ORC is known, some possibilities have been ruled out. First of all, since the place where the ORC exists is far from the galaxy, the possibility that it is the wreckage of a supernova explosion is excluded. In rare cases, a ring of radio radiation can be seen in galaxies due to the burst of star formation, but this is also denied because there is no galaxy on which star formation is based. Light emitted by the stars and galaxies appear brighter under the influence of gravity Einstein ring possibility of also been pointed out, but Norris as being too has a symmetry as the Einstein ring was denied.
In a paper to be presented at the Astronomical Society of Australia, Norris concludes that the ORC is 'something unknown' by examining the various identities of the ORC and denying any possibility. On top of that, ORC should investigate the possibility of being related to 'something that may exist but has not yet been observed' such as fast radio bursts .

In addition, as another possibility, ORC is that's what is called a wormhole throat (throat) is also pointed out .

From the ORCs discovered so far, it is estimated that there are about 1000 ORCs in the universe. The ORC is said to be very difficult to find, but researchers will continue to investigate it as it could significantly change the understanding of the universe.
