Astronomers discover fastest-growing black hole ever

A monster black hole has been discovered, and it's growing very fast (but it's far, far away) The fastest-growing black hole in the universe eats a sun every 48 hours - and Australian astronomers have found it

And it's growing so fast, it's able to devour the mass equivalent to our sun every two days.

With giant new ground-based telescopes now under construction, scientists will also be able to use bright, distant objects like this voracious black hole to measure the universe's expansion, the researchers said.

The quasar was found by poring over data from the ESA Gaia satellite, the NASA Wide-field Infrared Survey Explorer (WISE), and the ANU SkyMapper telescope.

This makes the monster black hole incredibly bright, outshining even a big galaxy.

According to Dr Wolf, if this monstrous black hole was at the centre of the Milky Way it would likely make life on Earth impossible with the huge amounts of x-rays emanating from it. Wolf further added that it would have appeared as an unbelievably bright "pin-point star", which could wash out almost every star present in the celestial sphere.

These shiny supernovas can be used as beacons to identify and study the formation of elements in early galaxies of the universe; scientists can see shadows of objects in front of a supermassive black hole.

For those trying to unlock the secrets of the universe, the bigger a black hole is, the better.

The researchers spotted light from the object in the near-infrared.

Space experts have detected the greediest supermassive dark opening experiencing the speediest development spurt around 12 billion years back.

USA endorses Kiev's raid on Russian news agency amid worldwide condemnation
Vyshynsky's colleagues at RIA Novosti-Ukraine said he was detained today near his home in Kiev, according to a report by the U.S. Vyshinski is a Ukrainian national who received a Russian passport in 2015 by presidential decree.

"During the birth of the universe, some really massive seeds were created that these black holes then formed around".

If it sat at the heart of our own galaxy, researchers say the supermassive black hole would wipe out any chance of life on Earth.

The breakthrough was made because of the precision of the European Space Agency's Gaia mission, which allows the Earth-bound SkyMapper to more precisely bypass the "contamination" from cool stars in the Milky Way, which may get in the way.

The team discovered it was growing at a rate of one percent every million years in the early stages of the universe, some 12 billion years ago.

Fortunately, Wolf points out that such huge and rapidly growing black holes seem to be very rare.

"We don't know how this one grew so large, so quickly in the early days of the universe", Wolf admitted.

The mega black hole that is said to be growing faster than any black hole in the universe today was found by scientists from the Australian National University (ANU).

Australian researchers have discovered what they've described as the fastest-growing black hole in the universe.
