Scientists have come to know about such a black hole, whose size is increasing every second as much as the size of our Earth. This is quite frightening, because no black hole grows so fast. According to the information, the mass of this giant black hole is 3 billion times the mass of our Sun. History suggests that other black holes of this size stopped growing billions of years ago, but they are still expanding. This black hole is about 500 times bigger than the Sagittarius A black hole in the heart of our galaxy. This black hole is so powerful that it can swallow the entire galaxy like a giant.

Researchers believe that this black hole is the fastest growing black hole in the last 9 billion years. In such a situation, the question arises that what can be the reason for expanding it till now? In this regard, lead researcher Christopher Onken, from the Research School of Astronomy and Astrophysics at the Australian National University (ANU), has said that this may have happened due to the collision of two large galaxies. This collision would have given off a lot of energy to make the black hole grow.

This black hole has been discovered in a sky survey conducted at Siding Spring Observatory in Australia. Although scientists have described this discovery as a needle in a haystack. Astronomers have been looking for such objects for the last 50 years. , but this astonishing black hole went unnoticed. The research paper related to this discovery has been presented in the Journal of the Astronomical Society of Australia. It has not been reviewed yet, but the preprint version has been made available through thearXiv database.
