Supermassive Black Hole At The Center Of The Milky Way Presents A Mysterious, Cool Gas Around It

Share

New research has revealed more never-before-seen details on the Sagittarius A, the supermassive black hole located in the deep space at the center of the Milky Way. Even though the black hole can’t be seen, scientists say it is there because of decades, given to scientific observations of the Milky Way, as well as many other data.

The extreme gravitational pull of the black hole pulls in almost everything, but nearby junk it hasn’t yet absorbed, circles in a shape known as ‘accretion disk.’ The new study unveils that besides the dust and super-heated gases, there is also a bend of similarly cooler gases present nearby.

The findings were published in a new paper in the journal Nature, and details the ring of cool gas that has never been discovered before. However, ‘cool’ might not be a proper term for it, as the gas is still scorching, at approximately 18,000 degrees Fahrenheit. This is a lot cooler than the 18 million degrees Fahrenheit of the rings of hot gas that have earlier been identified close to the supermassive black hole.

However, the process through which the different gases, as well as the dust and other junk in the accretion disk, have accumulated, and also the mechanisms at work inside the disk, remain an enigma. Moreover, the scientists are planning to further observe the core happenings of the region around the galaxy’s black hole, with the hope to discover more details about the process.

Elena Murchikova​, the lead author of the study, said in a statement that the team working on the discovery was the first to capture the mysterious disk and observe its orbit. The researchers are also observing accretion onto the Sagittarius A. This is reportedly crucial because this black hole is the closest supermassive giant to us.

Still, scientists have not much understanding of how the supermassive black hole’s accretion disk is functioning and hope that new observations would shed light on the process.
