SkyMapper Telescope Detects Fastest Growing Black Hole In The Universe

15 May 2018

The SkyMapper telescope, which Australian National University astronomers used to find the fastest-growing black hole known in the universe.

In this case, the researchers discovered the black hole which, according to their estimates, was as big as 20 billion suns and growing by a percent every one million years.

This supermassive black hole is the fastest-growing quasar in the known universe.

The black hole is estimated to be the size of 20 billion suns.

"It would appear 10 times brighter than a full moon and nearly wash out all of 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.

Mars Helicopter to launch as part of Nasa's 2020 mission
NASA considers the mission "a high-risk, high-reward project" and if it fails, it doesn't impact the rest of the rover's mission. The craft will be autonomous but will have a wireless connection to the Mars 2020 rover to exchange data.

The black hole was spotted by the SkyMapper telescope at the ANU Siding Spring Observatory in near infrared light with help from the European Space Agency's Gaia satellite.

Christian Wolf of the ANU's Research School of Astronomy and Astrophysics said.

While researchers were looking at the early universe, they stumbled upon this monster black hole. Wolf said that the reason is that the large amount of gases it takes in every day causes much heat and friction.

And it's a good thing this monster black hole isn't at the centre of our Milky Way. Apart from absorbing gases, it would have emanated all kinds of radiations that would have made life on Earth impossible.

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

Asian shares were mostly lower in muted trading Tuesday amid continuing uncertainty over trade tensions between China and the U.S. The ZTE case also drives home how entwined the USA and Chinese economies are. "Free and open trade, I think that's the solution.

However, the recently discovered monstrous black hole is so huge that, even if it had formed right after the Big Bang and expanded at the highest possible rate, it would have absorbed stars with masses higher than our Sun's mass by several thousands times to be as big as the astronomers observed it recently. Wolf said that with the expansion of the Universe, space gets expanded, which stretches the waves of light and transforms their color.

They looked at the quasar named SMSS~J215728.21-360215.1, and in its center, they saw a supermassive black hole that shines brightly.

The study, titled "Discovery of the most ultra-luminous QSO using Gaia, SkyMapper, and WISE", will be detailed in Publications of the Astronomical Society of Australia and the arXiv preprint is available online.

The capsule, he said, helped to confirm that the far-away object was a candidate to be a very large quasar.

Dr Wolf said it's "actually remarkably hard to find these very fast-growing and very massive black holes because they are rare and (it's) not easy to tell them apart from other stars in our Milky Way".
