Fastest growing black hole ever found eats a sun every 2 days


"The heat radiation from the matter falling into the black hole, which is the light we see, is a few thousand times brighter than our own Milky Way galaxy", Christian Wolf, the lead researcher on the university's team of astronomers, wrote in an email to CNN.

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.

Finding a black hole that eats the same amount of mass as our Sun every two days and shines thousands of times brighter than whole galaxies.that's just insane.

If it were at the center of the Milky Way, a full 100,000 light years from Earth, the enormous black hole would appear in the night sky 10 times brighter than the moon.

The big hole, codenamed QSO SMSS J215728.21-360215.1, is the staggering size of about 20 billion suns, and grows at a rate of 200 million suns over a million years.

We often think of a black hole as the darkest object in the universe, consuming even the light that comes near it. Data from European Space Agency's Gaia satellite helped discover the black hole, and the spectrograph on the ANU 2.3 meter telescope confirmed the discovery.

The researchers found the growing of a black hole ever found.




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

According to Wolf, this kind of black holes that are both fast-growing and incredibly large are "exceedingly rare" to find and could actually be used to measure the expansion of the universe. It would appear as an incredibly bright pin-point star that would nearly wash out all of the stars in the sky, "said Christian Wolf, lead author of the study and a researcher from the Australian National University".

The discovery could give us more insight into the Big Bang, Wolf said.

Even black holes get hungry. "We do not know how it grew so much and so fast in the first stage of the Universe", said the scientist. Pictured, a bright supermassive black hole.

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

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