Mysterious fire ring discovered outside our galaxy … Scientists reveal the secret of its existence | Science

Researchers hope to pursue more in-depth and comprehensive research to confirm the nature of the rogue supernova, which could be useful in improving scientists’ understanding of this type of substance.

An international team of scientists led by researchers at the University of Western Sydney in Australia has discovered a mysterious ring-like object near our Milky Way galaxy, which may be the first in astronomical history.

Mysterious circles

Just StudyPublished in monthly announcements, the researchers used the ASKAP or Australia’s Pathfinder Square kilometer line to achieve their findings.

ESCAP is a radio telescope located in the western part of Australia and consists of 36 antennas, each 12 meters in diameter, representing a large antenna covering an area of ​​4,000 square meters. Construction began in late 2009. And came into operation in 2012.

ESCAP was able to observe this mysterious ring outside the Milky Way galaxy known as the Great Magellanic Cloud (LMC), a galaxy 160,000 light years away from us.

Just Official report Published by the University of Western Sydney, the research team was surprised to find a celestial body of this shape outside the galaxy, at first they thought it was a “strange radio circuit” and spherical radio objects incomprehensible to radio circles. Discovered in 2019 and are believed to have originated from galaxies.

But after further study, scientists discovered that this mysterious ring may be the remnant of a star that erupted about 2200-7100 years ago, forming a giant supernova, the remnants of which erupted are still expanding, in light of the study’s estimate.

Rogue Supernova!

This means that, according to the research team, this is the first time a supernova has been detected outside the Milky Way, which is why they called this ring of fire “rogue”. It was as if the star had left the star galaxy in obedience.

According to a new study, the “Rogue” star appeared from the Great Magellanic Cloud millions of years ago, surrounded by a sub-star, one of which was in the red giant phase and the second in the white dwarf phase. . The second one had a strong gravitational pull so it pulled the red giant object very quickly.

As the material of the red giant accumulates rapidly and strongly on its dwarf companion, rapid and abrupt nuclear reactions occur on the surface of the white dwarf, and at one point it explodes, forming what is known as a “supernova Ia”.

Because of this strange situation, researchers in this group hope to carry out more in-depth and comprehensive research to confirm the nature of the rogue supernova, which will be useful in developing scientists’ understanding of this type of material.
