Using NEOWISE infrared data, astronomers tracked a massive Andromeda star, M31-2014-DS1, that brightened and then vanished over a few years, with optical/near-infrared follow-up supporting a direct collapse into a black hole without a supernova, a rare event that helps calibrate how massive stars end their lives.
Astronomers using JWST, Keck, the Very Large Array and Chandra X-ray data spotlight the “Infinity Galaxy,” a collision between two galaxies where a central black hole sits between the two cores and shows signs of active feeding. The team argues this could be a direct-collapse black hole formed in situ during the merger about 50 million years ago, potentially growing from a seed of a few hundred thousand solar masses to around a million, offering a rare glimpse of black-hole birth in action.
Astronomers using the James Webb Space Telescope discovered an unusual black hole in the Infinity Galaxy, challenging traditional theories of black hole formation by suggesting it may have formed directly from a gas cloud during a galaxy collision, which could reshape our understanding of early universe evolution.
Astronomers using JWST discovered the Infinity Galaxy, a collision of two galaxies with a black hole located between them, possibly formed directly from collapsing gas, providing evidence for a new black hole formation pathway and shedding light on early supermassive black hole development.
The James Webb Space Telescope (JWST) has discovered unexpectedly large black holes in the early universe, challenging existing theories of black hole formation. These black holes, observed in galaxies from just 330 million years after the Big Bang, are much larger than anticipated. One emerging theory suggests these supermassive black holes may have formed through "direct collapse" of massive gas clouds, bypassing the intermediate stellar phase. Further observations are needed to confirm this hypothesis and understand the origins of supermassive black holes.
