Webb Detects Most Distant Active Supermassive Black Hole to Date

Thousands of galaxies appear in this view, which is set against the black background of space. There are many overlapping objects at various distances. They include large, blue foreground stars, some with all eight diffraction spikes, and white and pink spiral and elliptical galaxies. Numerous tiny red dots appear throughout the scene. This is a portion of a vast survey known shorthand as CEERS.

Summary

With Webb, a slew of other distant black holes and early galaxies also popped into view for the first time.

It’s a bonanza! The universe is absolutely teeming with black holes. Researchers have long known this, but less massive black holes that existed in the early universe were too dim to detect – that is until the James Webb Space Telescope began taking observations. Researchers behind the Cosmic Evolution Early Release Science (CEERS) Survey are among the first to begin plucking these bright, extremely distant objects from Webb’s highly detailed images and data.

First up: The most distant active supermassive black hole ever found – just over 570 million years after the big bang. It is on the smaller side, more similar to the mass of the supermassive black hole at the center of our Milky Way galaxy than to the extremely large “monsters” we’ve glimpsed before with other telescopes. CEERS researchers also identified two more small black holes in the early universe, along with almost a dozen extremely distant galaxies. These initial findings suggest that less massive black holes and galaxies might have been more common in the early universe than previously proven.

Researchers have discovered the most distant active supermassive black hole to date with the James Webb Space Telescope. The galaxy, CEERS 1019, existed just over 570 million years after the big bang, and its black hole is less massive than any other yet identified in the early universe. Not only that, they’ve easily “shaken out” two more black holes that are also on the smaller side, and existed 1 and 1.1 billion years after the big bang. Webb also identified eleven galaxies that existed when the universe was 470 to 675 million years old. The evidence was provided by Webb’s ...
