The Black Hole At The Center Of Our Galaxy is Getting Hungrier Day By Day

Humans or animals or any living being could get hungrier if they’ve not eaten or they’re starved. But now it’s something else that possesses hunger. Well, I’m pretty certain that almost all of us know about black holes and also like to investigate them. Don’t get confused about what’s the relationship between hunger and Black Hole as you’re now close to check out one such black hole that has gone on a  hunger streak as time has gone by and is proceeding to.

Unseeable and inevitable, black holes already rank among the more sinister phenomena out in the cosmos.

Sagittarius A*, the supermassive black hole at the center of the Milky Way Galaxy appears to have consumed nearby matter at an unparalleled pace.

Astronomers have now verified that, over the last few years, Sgr A*’s most energetic X-ray flares are advancing. Andrea Ghez, a professor of physics and astronomy at the University of California, Los Angeles, and a senior author of the research said: “We have seen nothing like this in the 24 years we’ve examined the supermassive black hole,”. Ghez also continued that they don’t recognize what’s causing this black hole to go on such a feast, whereas normally these black holes are on a quiet diet.

Last year, the black hole flared 75 times its normal brightness in near-infrared – the brightest we’ve ever noticed it in those wavelengths.

Researchers led by astrophysicist Emmanuelle Mossoux of the University of Liège in Belgium found that the flares have multiplied threefold from 2014 till 2017.

“However, this did not change our global result: a change in flaring rate is located for the brightest and most energetic flares at the same date as was discovered in the previous section,” the Mossoux and colleagues wrote in their paper.

The black hole itself can not be seen because it operates as a one-way trapdoor, even for light. But it’s feasible to identify radiation blazing from gas and dust just outside the “event horizon” as they’re sped up towards their final fate.

The team also employed a technique called speckle holography to re-analyze older, fainter observations dating back 24 years, from which they confirmed that the level of brightness seen this year was unprecedented in the last quarter of a century.

Well, now arrives the prime challenge. Whether the black hole is getting in a new phase or it is just that we’ve looked at a few fireworks from unusual blobs of gas falling in, told Mark Morris, a professor of physics and astronomy at UCLA and the paper’s Co-senior author.

Many things and views are arising over this.

One is that the feeding frenzy is associated with the closest approach to the black hole of a star called S0-2 during the summer of 2018 and that an oversized volume of gas from the star could have reached Sagittarius A* this year.

Another possibility suggests a bizarre object attributed to as G2, which is probably a pair of binary stars, which made its closest approach to the black hole in 2014. It is viable the black hole could have stripped off the exterior layer of G2. A third proposal is that several large asteroids have been dragged into the cosmic sinkhole.

The black hole is about 26,000 light-years from Earth and presents no menace to our planet. Thus, we are harmless from this hunger growing black hole.

The research has been accepted by Astronomy & Astrophysics and is available on arXiv.
