    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.

    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 Cosmic Evolution Early Release Science (CEERS) Survey, led by Steven Finkelstein of the University of Texas at Austin. The program combines Webb's highly detailed near- and mid-infrared images and data known as spectra, all of which were used to make these discoveries.

    CEERS 1019 is not only notable for how long ago it existed, but also how relatively little its black hole weighs.

    This black hole clocks in at about 9 million solar masses, far less than other black holes that also existed in the early universe and were detected by other telescopes.

    Those behemoths typically contain more than 1 billion times the mass of the sun—and they are easier to detect because they are much brighter. (They are actively "eating" matter, which lights up as it swirls toward the black hole.)

    The graphic shows the redshift of one active supermassive black hole.

    At top right is the complete NIRCam image of the field, which has an uneven white outline and is very small.

    To its left is a large pull out, labeled NIRCam imaging, which shows galaxies of different colors, shapes, and sizes across most of the top row.

    A tiny open white box at far right, and a line drawn to a larger image at left.

    In the inset image is a larger blurry red dot with two green dots at its left and right.

    The pull out is labeled CEERS 1019, 13.2 billion years.

    The bottom row shows one line graph labeled NIRSpec Microshutter Array Spectroscopy.

    It shows data in white, a model in yellow labeled faster gas around the black hole, and a second model represented by a purple line that is labeled slower gas in the galaxy.
