What's unusual about this disk though is that it's deeply placed in the black hole's intense gravitational field, with its light being intensified and stretched by the black hole's powerful pull.
"The predictions of current models for gas dynamics in very faint active galaxies clearly failed", Bianchi added.
This is because the disc of material is deeply embedded in the black hole's intensely powerful gravitational field, to the extent that light emanating from it is distorted.
"We've never seen the effects of both general and special relativity in visible light with this much clarity", said team member Marco Chiaberge of AURA for ESA, STScI and Johns Hopkins University said in a statement. It's a test of Albert Einstein's theories of relativity, general and special.
So this type of black hole shouldn't exist but it does - making the behemoth, mysterious cosmic phenomena even more intriguing.
The black holes are located 2.5 billion light-years away from Earth, which means that they were actually hosted in an universe much younger than the one we now inhabit.

And I think it would be a rather curious thing to do if this is about taking back control to parliament, to actually shut it down. On Tuesday, lawmakers narrowly approved a measure that could make it harder for the next prime minister to suspend parliament.
Each one of those black holes has a mass over 800 million times than that of our Sun and the two of them are drawing closer and closer together in what has been called "a death spiral". The two black holes will continue to get closer to one another sending out large ripples in space-time, known as gravitational waves, which will be detected again on Earth.
There's something unusual happening at the center of the spiral galaxy NGC 3147, and the Hubble Space Telescope caught a good look.
Spectrograph are diagnostic tools that divides light from an object into its many individual wavelengths to determine its speed, temperature, and other characteristics at a very high precision. "So if you observe it from the ground, you're dominated by the brightness of the stars, which drowns the feeble emission from the nucleus".
The team's paper will appear online today in the Monthly Notices of the Royal Astronomical Society.
The Hubble telescopes is a collaboration between the USA space agency NASA and the European Space Agency (ESA). NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. Goulding, Mingarelli and collaborators from Princeton and the U.S. Naval Research Laboratory in Washington, D.C., report the discovery of July 10 in The Astrophysical Journal Letters.
Goulding, Greene and the other observational astronomers on the team detected the two titans with the Hubble Space Telescope.
