Super big black hole of the oldest universe ever found



Astronomers have discovered a large black hole that dates back almost to the dawn of creation.

It is the furthest black hole that has been found.

A team led by Eduardo Banados of the Carnegie Observatories reported in the journal Nature on Wednesday that the black hole is found in a quasar that dates from 690 million years of the Big Bang. That means that the light of this quasar has traveled our way for more than 13 billion years.

Banados said that the quasar provides an exclusive image of the baby of the universe, when it was only 5 percent of its current age.

would be like seeing photos of a 50-year-old man when he was 2 and a half years old, according to Banados.

"This discovery opens a new and exciting window to understanding the early universe," he said in an email from Pasadena, California.

Quasars are incredibly bright objects deep in the cosmos, driven by black holes that devour everything that surrounds them. That makes them perfect candidates to unravel the mysteries of the early cosmic times.

The black hole in this newest and farthest quasar is 800 million times the mass of our sun.

There are much larger black holes that are out there, but none so far, at least among those found so far. These larger black holes have had more time to grow in the hearts of galaxies since the Big Bang, compared to the newly observed young man.

"The new quasar is itself one of the first galaxies, and yet it already houses a giant black hole as massive as others in the current universe," said co-author Xiaohui Fan of the Steward Observatory at the University of Arizona , it's a statement.

At the time of this new quasar, the universe emerged from a kind of … called Dark Ages. First stars and galaxies appeared and their radiation ionized the surrounding hydrogen gas to illuminate the cosmos.

Banados suspects there are more examples like this, between 20 and 1

00.

"The newly discovered quasar is so bright and evolved that I would be surprised if this was the first quasar to have formed," Banados said. "The universe is huge and the search for these very rare objects is like looking for the needle in the haystack".

Only another quasar has been found in this ultra-distant category, despite extensive scanning. This newer quasar surpasses the holder of the previous record in about 60 million years.

Still waiting, astronomers do not know how close they will reach the true beginning of time, 13,800 million years ago.

Banados y su The team used the Carnegie Magellan telescopes in Chile, supported by observatories in Hawaii, the southwestern United States and the French Alps.
