Top 4 Coolest & Biggest Black Holes

NGC 1277

 This is the most massive black hole ever known. The supermassive black hole has a mass equivalent to 17 billion suns and is located inside the galaxy NGC 1277 in the constellation Perseus. It makes up about 14 percent of its host galaxy’s mass, compared with the 0.1 percent a normal black hole would represent

The giant black hole is about 11 times as wide as the orbit of Neptune around our sun. The mass is so far above normal that the scientists took a year to double-check and submit their research paper for publication. The event horizon is more than twice that of NGC 3842’s

And this black hole is powerful. Not only has it consumed an impressive amount of material, it is ejecting an amazing amount as well.

Researchers found that about 400 solar masses of material is streaming away from this object at speeds exceeding 4,970 miles per second (8,000 kilometers), which is more than five times more powerful than the previous record holder.

Ultimately, this black hole puts out about one hundred times the energy output by all of the stars in our galaxy, so it’s about 2 TRILLION times more energetic than the Sun!
