Australian astronomers find a cosmic 'monster' that's growing fast

5_15_Black Hole

A team of Australian scientists have just discovered a monster black hole that would be ready to engorge our Sun anytime.

The supermassive black hole, or quasar, is thought to have been present in the early universe - when our now 13.8-billion-year-old universe was around 1.2 billion years old - and is such a monster, it swallows the mass of our own sun every two days.

However, the supermassive black hole is at a distance of 12 billion light-years, meaning that what the astronomers saw happened 12 billion years ago.

Wolf said if it was at the centre of the Milky Way, it would appear 10 times brighter than a full moon as a pin-point star that would nearly wash out all the stars in the sky. "It would appear as an incredibly bright pin-point star that would nearly wash out all of the stars in the sky", said Dr. This black hole in the latest discussion has been spotted by the Gaia satellite of the European Space Agency, which calculated the small motions of the celestial bodies. This also helped with its detection as light waves from the black hole red-shifted during their long journey to Earth, allowing the astronomers to use ANU's SkyMapper telescope to detect them in near-infrared.

Dr Wolf said the energy emitted from this newly discovered supermassive black hole, also known as a quasar, was mostly ultraviolet light but also radiated x-rays. They believe objects like these are extremely rare but could be the key to gain more insight into the beginning and expansion of our universe.

Not that you'd know, because the x-rays emanating from it would make life on Earth impossible. The studied black hole reportedly draws off light of large amounts thereby outshining the entire galaxy.

"As the Universe expands, space expands and that stretches the light waves and changes their colour", Dr Wolf said. Wolf further added that the research is still going on to hunt for more faster-evolving black holes.

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.

A black hole is an intense gravitational pull that sucks in everything in its path, including light.

The new work was accepted to the journal Publications of the Astronomical Society of Australia.

In addition, these fast-growing quasars help clear the fog around transiting objects, "which makes the universe more transparent", said Wolf.

"As supermassive black holes shine, they can be used as beacons to see and study the formation of elements in the early galaxies of the universe".
