The James Webb Space Telescope detected what may be the oldest known black hole in the universe by deconstructing faint glimmers of light from close to the dawn of time.
The James Webb Space Telescope has spotted the earliest known black hole in the universe, and astronomers think even earlier ones could have swarmed the young universe.
Black holes are born from the collapse of giant stars and grow by ceaselessly gorging on gas, dust, stars and other black holes. For some of the gluttonous space-time ruptures, friction causes the material spiraling into the black holes' maws to heat up, and they emit light that can be detected by telescopes — turning them into so-called active galactic nuclei .
How black holes formed so suddenly in the early universe remains a mystery. Astronomers are still on the hunt for even younger, hypothesized"primordial" black holes, which came into being very soon after — or, according to some theories, even before — the Big Bang. But so far, they remain elusive.

Best of Last Week—Biggest black hole, recovering lithium from batteries, how social networks shape decision-makingIt was a good week for space research as a team of astronomers at Durham University, working with one colleague from the Max Planck Institute for Astrophysics and another from NASA Ames Research Center, reported that light-bending gravity revealed one of the biggest black holes ever found, more than 30 billion times the mass of the sun. Also, a combined team from Northwestern University and Tsinghua University adapted a well-known computer-vision algorithm to sharpen photos blurred by the Earth's atmosphere. They also trained it using an AI application. And an international team of astronomers using data from NASA's James Webb Space Telescope, confirmed that giant planet atmospheres in the Milky Way galaxy vary widely.
