If dark stars existed, they would have been capable of forming in the universe before ordinary stars could have formed. When ultradense cores of dark matter are exhausted, it is theorized that dark stars could collapse to form the massive "seeds" for supermassive black holes.

Astronomers find galaxy Y1, a young star-forming region, revealing extreme heat just 600 million years after the Big Bang.

New observations from the James Webb Space Telescope have revealed unexpected features in the early universe, including unusually bright galaxies, rapidly forming black holes, and compact objects that defy conventional explanations.

In the season 2 episode "Mirror, Mirror," Star Trek perfected the alternate universe trope long before Hollywood's multiverse obsession.

Using JWST's Mid-Infrared Instrument, the scientists honed in on stars, all between one and eight times the mass of the sun, that are late in their lifetimes. These are called asymptomatic giant branch (ASB) stars at the red giant phase of existence, before they explode and collapse into white dwarfs.

A s the James Webb Space Telescope (JWST) continues to peer into the origins of our universe, it’s delivering a steady stream of discoveries back on Earth. One of the latest: the explosive death of a star when most were only beginning to be born.

The James Webb Space Telescope has picked up the light from a massive star that exploded about a billion years after the birth of the universe

Scientists at the University of Missouri have identified a small group of unusual objects in the early universe. Using NASA's James Webb Space Telescope (JWST), Haojing Yan and his team at Mizzou's College of Arts and Science spotted these strange objects,

Mysterious blasts of radio waves from across the universe called fast radio bursts help astronomers catalog matter. ESO/M. Kornmesser, CC BY-SA If you look across space with a telescope, you’ll see countless galaxies, most of which host large central ...

Scientists have identified a strange cosmic relic called Cloud-9 — a starless, gas-filled object dominated by dark matter.

A recent study provides answers to three seemingly disparate yet pressing cosmic dawn puzzles. Specifically, the authors show how dark stars could help explain the unexpected discovery of "blue monster" galaxies,
