It’s a collision of mind-bending proportions, happening in a distant region of the cosmos, and it appears to have given birth to a monster.

Astronomers have observed a supermassive black hole forming from the collision of three galaxies 1.8 million light years away from Earth.

The enormous object dwarfs anything in our galactic neighbourhood, with scientists estimating its mass to be 3.8 billion times that of our sun.

For comparison, the supermassive black hole at the centre of the Milky Way is around 4.3 million times the mass of the sun, making the object an absolute monster.

In a paper published online in the journal Monthly Notices of the Royal Astronomical Society, Australian astronomers describe the object, which was found during a test of a new telescope from Australia’s scientific body CSIRO in Murchison.

Focusing on a stellar cluster called IRAS 20100−4156, which is made up of three spiral galaxies currently smashing into one another, the team was able to capture measurements of radio waves being emitted by the gas at its centre.

The observations were made using CSIRO’s new Australian Square Kilometre Array Pathfinder (ASKAP) telescope and the Australia Telescope Compact Array (ATCA).

Using the two telescopes provided two perspectives of the same region of the universe.

Closer inspection of the swirling gasses revealed they were moving at around 600 km per second – twice as fast as would have been expected.

The researchers explained that this is indicative of the scale of gravity exerted by the supermassive black hole as it accelerates material around its edge, which gives some indication of its mass.

Lisa Harvey-Smith, an astrophysicist at CSIRO Astronomy and Space Science and lead author of the paper, told ABC News: ‘This very fast motion of the gas tells us about how massive the black hole is.’

‘The really exciting thing about this is it is a direct measurement of the mass of the black hole by stuff that’s swirling around it.’

While the object is huge, physicists believe the largest black holes in the universe may be able to achieve masses of up 40 billion solar masses or more.

i dont think we can even comprehend that size..

” physicists believe the largest black holes in the universe may be able to achieve masses of up 40 billion solar masses or more.”

or that..

  1. One wonders how they can measure such incredible distances even with a hint of accuracy without any trigonometry .
    The distance could be fake .
