About 3.5 billion light-years away, there are two supermassive black holes that are locked in one of the most extreme orbital dances that are present in the Universe.
Their flaring death spiral has been documented for decades now.
New observations about the black holes are out
There are various new observations in which astronomers managed to detail the way in which these black holes are whirling about each other in the center of the galaxy called OJ 287.
The characterization has helped to refine the understanding of whether or not black holes are “hairy” – it seems that this issue has been puzzling cosmologists for decades now.
Science Alert notes that the OJ 287 is not an ordinary galaxy, but it’s a blazer that has a highly variable active galactic nucleus and also a relativistic jet that’s beaming the planet.
More than that, for more than a century, it’s been documented that it has been spitting out dazzling flares of radiation at semiregular intervals.
It’s been revealed that at the core, the OJ 287 is more intense than the most galactic nuclei. This has not one but two supermassive black holes and these are “chonkers” as the online publication mentioned above calls them.
“The smaller of the two would power a very respectable galactic nucleus in its own right, coming in at 150 million times the mass of the Sun. Our own Milky Way’s supermassive black hole is 4 million solar masses,” according to the notes.
The same notes reveal that the larger of the two “is one of the most massive black holes we’ve ever seen. It tips the cosmic scales at 18 billion solar masses,” Science Alert notes.

In other black hole-related news, according to recent reports, an astronomer believes that he spotted a stellar corpse known as a white dwarf that’s sending out blazes of light – these are a sort of mayday signals from the close orbit of a black hole.
