NASA discovers a ‘fast-growing black hole’ linked to galaxies


Astronomers have found evidence of a “fast-growing black hole” in the early universe, according to NASA.

This discovery has been called a “crucial missing link” because it could help us understand the connection between the first supermassive black holes and young galaxies.

NASA explained: “Astronomers have identified a rapidly growing black hole in the early universe that is believed to be a crucial ‘missing link’ between young star-forming galaxies and early supermassive black holes, using the data from the Hubble Space Telescope to make this discovery.”

The US space agency has also released an artistic impression of a supermassive black hole as well as an image taken by the Hubble Space Telescope.

NASA continued: “This artist’s impression is of a supermassive black hole that sits inside the dust-shrouded core of a vigorously star-forming ‘starburst’ galaxy.

“It will eventually become an extremely bright quasar once the dust clears.

“Discovered in a Hubble Deep Sky Survey, the dusty black hole dates back just 750 million years after the Big Bang.”

Quasars are extremely bright objects in the universe that are believed to be powered by black holes.

NASA dubbed the black hole GNz7q and said it lurked like a “monster” in a well-studied area of ​​the sky.

Current theories predict that black holes begin life in dusty galaxies before becoming quasars.

GNz7q has the qualities of both and that’s why it’s called the “missing link” that could help prove the theory.

The black hole is said to date back to a time when the universe was only 750 million years old.

Experts believe the universe is now around 14 billion years old.

Seiji Fujimoto, lead author of the Nature paper describing the discovery, said: “Our analysis suggests that GNz7q is the first example of a rapidly growing black hole in the dusty core of a star-shaped galaxy at a near time. of the first known supermassive black hole. In the universe.

“The properties of the object across the electromagnetic spectrum are in excellent agreement with predictions from theoretical simulations.”

Fujimoto said the black hole “provides a new avenue for understanding the rapid growth of supermassive black holes in the early days of the universe.”

Adding: “Our discovery provides an example of precursors to the supermassive black holes we observe in later epochs.”
