Astronomers at the Australian National University (ANU), led by Dr Christian Wolf of the Research School of Astronomy and Astrophysics, found the fastest-growing black hole known in the universe by looking back more than 12 billion years to what they call "the early dark ages of the universe".
"It would appear 10 times brighter than a full moon and nearly wash out all of the stars in the sky".
If this bright black hole would have been in our galaxy, astronomers say that it would outshine all the stars in the sky. The finding was ultimately confirmed with the help of a spectrograph in the Siding Spring Observatory of the university. "It would appear as an incredibly bright pin-point star that would nearly wash out all of the stars in the sky", said Dr. Experts said if the black hole exists in the Milky Way galaxy, life would be impossible on Earth.
A "supermassive" black hole swallowing up the mass of our sun every two days has been found by Australian astronomers.
As Dr. Christian Wolf of the Australian National University explained, this finding represents a big problem for astrophysics which, until now, was pretty much sure that supernovae turn into black holes which are up to 50 solar masses and can not exceed this limitation.
Apparently, what baffled the scientists was that this black hole expands at such an accelerated pace that, in accordance to the current theories, it must have about 20 billion times the mass of our Sun.
"As the Universe expands, space expands and that stretches the light waves and changes their colour", Dr Wolf said.
Now scientists are on the hunt for another black hole that might beat out this black hole's appetite and give them a glimpse into the inner workings of the universe only a few billion years after it formed.
Do you believe that black holes are more than just monsters that devour anything in the universe?
Though the team has no idea how this monstrous black hole grew so big when the universe was still in its infancy, they plan to continue their search for other fast-growing black holes, possibly faster than this one, in the universe. It is very far away.
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.
