'This is one of the most extraordinary black hole systems I've ever come across,' James Miller-Jones said.
An international team of astronomers has observed a never-before-seen phenomenon taking place at an “extraordinary” black hole, according to a study published in the journal Nature.
The black hole—which has a mass about nine times that of our sun—is located in a double-star system known as V404 Cygni, roughly 7,800 light years from Earth. Essentially, the black hole is in a 6.5-day orbit with a normal star about 70 percent the mass of the sun. Using the Very Long Baseline Array—an intercontinental system of 10 radio telescopes operated from a center in Socorro, New Mexico—the team observed the jets at a high resolution, equivalent to seeing a quarter in New York from the distance of Los Angeles.
“Because the axis about which the black hole was spinning was not the same as the axis of the binary orbit, the puffed up disk was forced to wobble about the black hole spin axis like a spinning top that is slowing down,” Miller-Jones said.
