Scientists found a colossal black hole near the dawn of time

gave The James Webb Space Telescope The most distant supermassive black hole ever detected — a the location The vortex is far from home, it's in one of the first galaxies in the universe.

Black holes were little more than that. A view from 50 years ago — a difficult mathematical answer to a physics problem — but even astronomers at the top of their field weren't entirely sure they existed.

Today, not only are supermassive Black holes Accepted science, they are achieving. Photographs taken Through a collection of multiple, synchronized radio dishes on Earth. Webb, the leading infrared space observatory, is also doing its part to reveal how these mysterious behemoths form in the first place. The search was done recently. published In the journal The nature And highlighted by NASA During this Black Hole Week campaign

A supermassive black hole was found at the center. GN-z11an extremely bright galaxy that was alive when the universe was only 430 million years old, a fraction of its current age, which is around 14 billion.

Black holes are the most incomprehensible phenomena in outer space. They do not have surfaces, like planets or stars. Instead, they have a range called “Event Horizon“Or a point of no return. If something swooped in too close, it would fall in, never to escape the hole's gravity.

The most common type, called A stellar black hole, thought to be the result of a massive star dying in a supernova explosion. The star's material then collapses in on itself, condensing into a relatively small area.

But how? Great Black holes, millions to billions of times more massive than the Sun, the shape is even more attractive than typical stellar black holes. Many astronomers and cosmologists believe that these invisible giants exist at the center of virtually all galaxies. There are recent Hubble Space Telescope observations. Reinforced the theory. That supermassive black holes originate in the dusty cores of starburst galaxies, where new stars are rapidly accreted, is still being teased out by scientists.

Mashable Light Speed

Using the web, a team of scientists was able to determine that GN-z11 has a central black hole with little evidence.

“We found very dense gas, which is common in the surroundings of massive black holes,” said principal investigator Roberto Maiolino of the University of Cambridge in the UK. In a statement. “These were the first clear signatures that GN-z11 is hosting a black hole that is perturbing.”

Next, the team found traces of electrically charged chemicals that are commonly found near active supermassive black holes. Scientists also saw ancient galaxies being blasted by a powerful wind, which is associated with supermassive black holes with supermassive black holes.

Taking all these clues together, the team believes that GN-z11 has a central black hole as massive as 2 million Suns.

Another team of researchers is studying this ancient galaxy for evidence of first-generation stars, so-called “Population III“Stars Stars with ambiguous names It is believed to have formed in the early universe before the existence of elements heavier than helium.

Most of the elements in the universe come from exploded the dead Starsso scientists have inferred that the first stars to be born were probably composed almost entirely of hydrogen and helium. Ancient material That came out of the Big Bang.

Scientists have theorized that they can find clusters of helium around massive galaxies from the earliest ages. The thought is that these ancient pockets of gas could collapse to form Population III star clusters. The team Thinks he's seen such a bunch. In the halo around the galaxy.

Finding evidence of these stars could be one of the most important discoveries in modern astrophysics.
