Radio images of the sky have revealed hundreds of "baby" and supermassive black holes in distant galaxies, with the galaxies' light bouncing around in unexpected ways.
But our research, published in the Monthly Notices of the Royal Astronomical Society , found a surprising population of galaxies whose light changes much more quickly, in just a matter of years.
Astronomers think there's a supermassive black hole at the center of most galaxies. Some of these are "active," which means they emit a lot of radiation. Their powerful gravitational fields pull in matter from their surroundings and rip it apart into an orbiting donut of hot plasma called an "accretion disk."

If 'stupendously large' black holes, those with masses more than 100 billion times that of the Sun, exist in the Universe, they would provide a powerful tool for cosmological tests due to their unique imprints, according to a paper published in the Monthly Notices of the Royal Astronomical Society .

A supermassive black hole suddenly vanished. Scientists think it's floating through space.
A supermassive black hole earlier believed to be situated in the centre of a far off galaxy has suddenly vanished
Black holes continue to elude scientists, with a lot about the celestial objects still shrouded in mystery. Now, a cosmic event has shaken astronomers!

Researchers across universities in North America spotted the space event.
According to scientists, every galaxy in the universe has at least one giant black hole at the centre. This includes our very own Milky Way.
Recently, a team from the University of Michigan published a study about recoding black holes in the American Astronomical Society Journal.
Lead by Dr Kayhan Gultekin, the team found that a black hole had suddenly went missing.
Many things are taking place:

A 'super telescope' that combines the powers of four separate telescopes has spotted a dim star dancing close to the supermassive black hole at the Milky Way's centre.
To observe objects near the black hole, the GRAVITY instrument at the Very Large Telescope in Chile combines infrared light from the facility's four eight-metre telescopes to achieve better sensitivity and resolution than can be provided by the individual components.
Extreme Black Holes Have Gravitational Hair that Can Be Measured, Physicists Say | Astronomy,
Gravitational-wave detectors can be used to measure gravitational-field hair of extreme black holes, according to a paper published in the journal Physical Review D .

"We discovered that extreme black holes — those that are saturated with the maximum charge or spin they can possibly carry — violate black hole uniqueness, the so-called no hair theorem," said lead author Dr. Lior Burko of Theiss Research and colleagues.

The researchers concluded that the red giant appears to be dancing with an unseen partner. The team wrote: "The simplest explanation for the dark companion is a single compact object, most likely a black hole, in the 'mass gap.'"
Exactly what determines whether a star explodes as a supernova or collapses into a black hole isn't clear. "The actual physics of the supernova explosion is a huge unknown," Thompson says. The black-hole mass gap "could be a vital clue to that process."
Marvelous and the Black Hole Review: A Sweet But Slight Comedy – /Film
Written and directed by Kate Tsang ( Steven Universe ) in her feature directorial debut, Marvelous and the Black Hole is sweet but slight coming-of-age dramedy about a troubled teen finding the magic in, well, magic. Tsang’s background in the animation world gives the film a bit of zest that elevates it from its standard coming-of-age trappings, but apart from a kooky performance from Rhea Perlman , Marvelous and the Black Hole is an inoffensive but adequate odd-couple comedy.
