What started as the size of about 20 billion suns has grown one percent every million years, into the cosmic behemoth we know now.
"If we had this monster sitting at the centre of our Milky Way galaxy, it would appear 10 times brighter than a full moon", Wolf added.
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.
Dr Wolf said: "The European Space Agency's Gaia satellite, which measures tiny motions of celestial objects, helped us find this supermassive black hole". In fact, the supermassive black hole is so far away that its ultraviolet light red-shifted before it reached our planet and was picked up by the SkyMapper telescope at the ANU Siding Spring Observatory.
If this shining, feeding black hole, also called a quasar, were at the center of our Milky Way, it would likely make Earth uninhabitable due to the X-rays emitted by it, Wolf added in the Australian National University statement.
"That one has a mass of 5 million solar masses - that is 40,000 times less mass than the one that we have now found", Dr Wolf says.
This makes the newfound giant black hole the fastest-growing quasar in the known universe.
"While objects of this luminosity are exceedingly rare in the Universe, they are particularly valuable as bright background and reference sources in order to study the properties of intervening matter along the line-of-sight, and for directly probing the expansion of our Universe with new instruments in the coming decades", the authors reported. Also, there's no reason to panic according to Dr. Wolf.
Do you believe that black holes are more than just monsters that devour anything in the universe?
"We don't have to be afraid of that".
The capsule, he said, helped to confirm that the far-away object was a candidate to be a very large quasar.
After traveling for more than 12 billion years, the quasar's light was detected by the SkyMapper in the near-infrared spectrum. That would be right after the Big Bang.
The findings have been accepted for publication in the Publications of the Astronomical Society of Australia (PASA).
"And it might mean that there were seeds to these black holes in the very early universe".
Wolf painted a vivid picture of what the supermassive black hole would look like from Earth if it were located in the center of our galaxy.
