Astronomers Discover Mysterious Circular Ring near our Neighboring Galaxy


Published on: May 19, 2022,

Researchers from Sydney University researchers have discovered a mysterious circular ring near our neighboring galaxy that could be remains of an exploded star that could be 7,000 years old. It could be first known case of intergalactic supernova remnanat.  Scientists have named it J0624–6948 and it is mostly located in the Large magnetic cloud which is satellite galaxy of the milky way. Scientists have said the discovery was exciting and raised many unanswered questions.


“ When the almost perfectly circular radio object we thought it was yet another ORC but after additional observations it became clear that this object is much likely to be something else,” said Professor Filipovic. The ring that was discovered has significant differences to five other known ORCs. Professor Filipovic added, “ The most plausible explanation is that the object is an intergalactic supernova remnant due to an exploded star that resided in the Large Magelllanic cloud.”


It is thought this is a remnant of super flare activity form a nearby Milky Way star. It is thought to be be 2200 to 7100 years old. J0624–6948 was first detected with Australian Square Kilometre Array Pathfinder (ASKAP) managed by CSIRO. It is one of several new generation radio telescopes that are revealing new features of the Universe.
