Astronomers have discovered an enormous black hole— and quite possibly the most massive one ever found. But don’t worry; it’s nowhere near our Milky Way galaxy. The Independent has more.


The gigantic black hole was discovered in a galaxy about 220 million light years from Earth. The average black hole takes up just one tenth of a percent of a galaxy’s mass, this one takes up 14 percent.


That’s big. What makes this black hole so special is the size of the tiny galaxy it resides in, called NGC 12-77.  Fox News reports the black hole makes up an incredible amount of its host galaxy’s mass—that of about 17 billion suns.


Study team member Karl Gebhardt of the University of Texas at Austin said…
"This is a really oddball galaxy…It's almost all black hole. This could be the first object in a new class of galaxy-black hole systems."


He continued, saying…

“When it first popped up we said we don’t believe it. There’s just no way. Something’s wrong.
“That’s the part of science that is so exciting, when you find something unexpected.”



And the BBC reports spotting a black hole can be tricky business since they swallow all light in their vicinity and virtually can’t be seen.


“Instead, astronomers measure the black holes' "sphere of influence" - the gravitational effects they have on surrounding gas and stars.”


In this video by Space.com, the animation depicts the orbit of the newly discovered super massive black hole. One second represents 22 million years of time in the simulation.


Most galaxies have a black hole at their center— ours is called Sagittarius A. And with NGC 12-77 being about just a quarter of the size of our own galaxy, its black hole is about 4,000 times bigger than ours.
