Potential smoking gun signature of supermassive dark stars found in JWST data

General Articles / By / 2 October, 2025

The first stars in the universe formed out of pristine hydrogen and helium clouds, in the first few hundred million years after the Big Bang. New James Webb Space Telescope (JWST) observations reveal that some of the first stars in the universe could have been very different from regular (nuclear fusion-powered) stars, which have been …

Slim Boom. Credit: Phil Drury, University of Sheffield An explosion the size of our solar system has baffled scientists, as part of its shape—similar to that of an extremely flat disk—challenges everything we know about explosions in space. The explosion observed was a bright Fast Blue Optical Transient (FBOT)—an extremely rare class of explosion which …

This illustration shows the ingredients of a long gamma-ray burst, the most common type. The core of a massive star (left) has collapsed, forming a black hole that sends a jet of particles moving through the collapsing star and out into space at nearly the speed of light. Radiation across the spectrum arises from hot ionized gas (plasma) in the vicinity of the newborn black hole, collisions among shells of fast-moving gas within the jet (internal shock waves), and from the leading edge of the jet as it sweeps up and interacts with its surroundings (external shock).
