The black hole was detected by Eduardo Bañados of the Observatories of the Carnegie Institution for Science, who was scouring surveys of the sky to look for ancient objects like this one.
It's a truly gargantuan black hole, some 800 million times the mass of our sun. As more giant telescopes are constructed, we'll be able to locate more of these objects, but this specific supermassive black hole gives us unique insight into the state of the early universe, as it existed shortly after the Big Bang.
Even in the most generous and optimistic estimate of the formation of black holes, creating such a massive one in such a relatively short period of time would be impossible. This is the most distant quasar-a supermassive black hole surrounded by a disk of gas-ever identified and it will help astronomers to better understand exactly how black holes grew when the universe was first forming.
Tennessee set to hire Alabama DC Jeremy Pruitt
The school walked back a contract offer to Greg Schiano after Volunteers fans overwhelmingly criticized the move. The 43-year-old assistant played college ball at Middle Tennessee before transferring to Alabama .
At a distance of about 13 billion lightyears, the most distant supermassive black hole known so far has been spotted by an worldwide team of astronomers.
Bañados and colleagues explored another possibility: If you start at the new black hole's current mass and rewind the tape, sucking away matter at the Eddington rate until you approach the Big Bang, you see it must have initially formed as an object heavier than 1,000 times the mass of the sun.
London's air pollution cancels out benefits of exercise, study says
Study participants spent two hours in a day by walking along Oxford street in London, or walking through Hyde Park . Air pollution is a phenomenon that affects other cities including Lagos, Abuja, Kano, Port Harcourt, among others.
But there's a problem with the finding: the black hole appears to be far too big for its age. Then, the neutral hydrogen was ionized by the first quasars, which are supermassive black holes at the center of galaxies. The light of the newly discovered most distant quasar yet carries crucial information regarding one of the earliest phases of the universe, the so-called reionization phase. Redshift refers to the lengthening of the wavelength of light from an object, caused by the Doppler effect as the universe expands.
"What we have found is that the universe was about 50/50 - it's a moment when the first galaxies emerged from their cocoons of neutral gas and started to shine their way out", Simcoe says. It also did this extremely fast, at least by the standards of the universe, which scientists have estimated is 13.8 billion years old. These can not, in theory, have formed from the collapse of massive stars because the timescales don't match-there would not have been enough time for a start to be born, live and die for it to exist. As stars and galaxies began to fire up and release energy, the photons they emitted ionized the neutral hydrogen gas that previously filled the universe, marking a fundamental turning point in history. It dates back to 690 million years after the Big Bang. It's thought that black holes grow by accreting, or absorbing mass from the surrounding environment.
There is one large mystery that remains to be solved: How did a black hole of such massive proportions form so early in the universe's history? By way of comparison, Earth is about 4.5 billion years old. After the energetic particles from the Big Bang cooled, they formed neutral hydrogen.
VW Executive Gets 7 Years In Prison In Emissions Cheating Scandal
But his lawyers point out that he wasn't involved when the scheme was hatched years earlier by the company. Federal courts have ordered Volkswagen to spend more than $1 billion to buy back or fix the affected cars.
