Scientists have found the growing black hole

Scientists have found the growing black hole

They have found that the void is devouring a mass of the universe every two days which is the equivalent to our sun.

Astronomers at Australian National University have just discovered an enormous black hole that shines.

5. If placed at the centre of the Milky Way, the galaxy that contains our solar system, this black hole will be 10 times brighter than a full moon and the brightest of all stars.

In fact, the light emitted would be so bright that it would wash out nearly all the stars in the sky, Wolf said.

Luckily, this black hole is too old and too far away to affect Earth, but that doesn't make its discovery any less remarkable.

Because of its distance and the expansion of space, that light had shifted into the near-infrared during its billions-of-years journey.

The black hole was detected by the SkyMapper telescope of the ANU Siding Spring Observatory, located about 480 kilometers northwest of Sydney, with the help of the Gaia satellite of the European Space Agency.

The powerful shining lights of these quasars and the black holes inside them act as beacons, the researchers say - the way they ionise gases around them can make the Universe more transparent to our telescopes.

To follow this black hole's evolution, ANU had to go far back in cosmological history to when the universe was about 2 billion years old.

Dubbed J215728.21-360215.1, the supermassive black hole was recently noticed by the before-mentioned Dr. Wolf and his colleagues.

At that time, this supermassive black hole was estimated to be the size of about 20 billion suns.

"As the universe expands, space expands and that stretches the light waves and changes their color", said Christian Wolf, the lead author of the study.

The supermassive black hole is so powerful, that if it were at the centre of the Milky Way, all life on earth would be impossible.

As the black hole rips a star apart, it emits intense energy jets, a.k.a. quasars (which are believed to be the brightest objects in the Universe) that help scientists infer the mass, the size, and other useful data about the black hole.

Not only would the light from this black hole be blinding to those looking to the night sky, its radiation would be so powerful that it might have killed all life on Earth.

Dr Wolf said that instruments on very large ground-based telescopes being built over the next decade.

"Perhaps this is already telling us something about rather unusual processes close to or related to the Big Bang", he said.

Dr Wolf said one benefit from finding black holes is they act as backlighting to everything else out in the cosmos, making it easier to see.
