Astronomers discover fastest-growing black hole ever

"The heat radiation from the matter falling into the black hole, which is the light we see, is a few thousand times brighter than our own Milky Way galaxy", Christian Wolf, the lead researcher on the university's team of astronomers, wrote in an email to CNN.
He said the record-breaking hole had been "hiding in plain sight" until about two weeks ago, when the European Space Agency released data that made it easier to identify black holes among the stars.
"Again, if this monster was at the center of the Milky Way it would likely make life on Earth impossible with the huge amounts of X-rays emanating from it".
The supermassive black hole, also known as a quasar, is very ancient. It would appear as an incredibly bright pin-point star that would nearly wash out all of the stars in the sky, "said Christian Wolf, lead author of the study and a researcher from the Australian National University".
Supermassive black holes are incredibly dense areas in the centre of galaxies with masses that can be billions of times that of the sun.
"And it might mean that there were seeds to these black holes in the very early universe".
Australian researchers have discovered what they've described as the fastest-growing black hole in the universe.
Luckily, this black hole is too old and too far away to affect Earth, but that doesn't make its discovery any less remarkable. "We don't know how this one grew so large, so quickly in the early days of the Universe", Wolf said. New land-based telescopes being built over the next decade might able to directly measure the expansion of the universe using these bright black holes.
"Scientists can see the shadows of objects in front of the supermassive black hole", Wolf said.
