LONDON – Giant black hole known to have a terrible reputation. In pop culture, black holes are depicted as pitch dark and always hungry.
They slide through the Universe sucking in everything they put their way through, and growing bigger because of it.
Because of this description, people think supermassive black holes are the oldest and hungriest kind.
It’s just that the BBC says that in reality, black holes aren’t that scary. They’re actually not very efficient at accreting or sucking up material around them, even in the dense galactic cores.
In fact, destroyed stars grow very, very slowly, they can’t possibly become supermassive just by sucking in new material.
The black hole inside CEERS 1019 is more similar to the black hole at the center of the Milky Way galaxy, which has a mass of 4.6 million times that of the sun. Scientists discovered this black hole while conducting the Early Release Science Survey of Cosmic Evolution (CEERS) led by Steven Finkelstein of the University of Texas at Austin.
This black hole continues to expand by consuming the surrounding interstellar gas and dust. Black holes form when the center of a very massive star collapses, leaving a vacuum where no light can enter or exit.
The project also discovered two more black holes in the galaxies CEERS 746 and CEERS 2782, which are slightly larger, weighing 10 million times the mass of the Sun. Astronomers call the three CEERS their light weight aiding understanding of how supermassive black holes formed and grew during the first billion years of the universe’s formation.
“This is very important because the universe was thrown into a thick ‘haze’ during this period, known as the Reionization Era,” the researchers said.
Today in the universe, neutral gases become ionized over hundreds of millions of years, making them transparent to ultraviolet light. What causes these periods is unclear, although it is something astronomers hope JWST can answer.
“Researchers have known for a long time that there must have been lower mass black holes in the early universe. However, the Webb telescope was the first observatory to capture its shape so clearly,” said Dale Kocevski of Colby College in Waterville, Maine.
