Researchers at the Australian National University (ANU) have discovered what they claim is the fastest growing black hole in nine billion years.
The same university reports in one press release.
According to researchers, the black hole is devouring the mass of the Earth every second.
It would also shine 7,000 times brighter than any other light from our galaxy – something that would make it possible for any well-equipped astronaut to observe in a dark backyard.
The researchers described the discovery as “a very large and unexpected needle in a haystack.”
Astronomers have been searching for such things for more than 50 years. They’ve found thousands that shine fainter, while this has gone unnoticed under the radar, says search leader Christopher Onken in the press release.
Three billion times that of the sun
in the studywhich has not yet been reviewed, researchers estimate that the black hole – J114447.77-430859.3, or J1144 for short – has a mass three billion times the mass of the Sun.
Numerous observations give clear indications that such supermassive black holes exist in the central regions of most galaxies. We don’t know for sure how it was formed.
to me Norsk Lexicon Store One possibility is that it was formed at the same time that galaxies are in the middle of it.
According to the research leader, all previously observed black holes of similar size date back to the largest in the history of the universe. These must have stopped growing at the same rate several billion years ago.
The reason for the strong brightness is currently unclear.
Two large galaxies may have collided, channeling large amounts of gas into the black hole, Onkin speculates. Watchman.
Plain near the Milky Way
The discovery was made when researchers noticed what is described as extremely bright Kvassar As part of the Skymapper project – a collaborative project between the Australian Astronomical Observatory and a number of Australian universities.
According to Store Norske Leksikon, there are many indications that quasars are supermassive black holes that capture the surrounding matter.
Black holes are not visible in the sky. The radiation of enormous power comes from the material on the outside, which heats up exponentially on its way inside.
The researchers believe that J1144’s position may be a contributing factor to its failure to describe it previously.
“People have historically avoided looking too close to the Milky Way, because there are so many stars and so much pollution in the way that it’s hard to find anything further,” Onkin says.
