The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

Astronomers have discovered a vast, dense cluster of massive galaxies just 1 billion years after the Big Bang, each forming ...

Dozens of dwarf galaxies swarming around the Andromeda Galaxy like bees have been caught on camera by the Hubble Space Telescope, which took more than a thousand orbits of the Earth to take enough ...

The "Cosmic Grapes" galaxy formed just 900 million years after the Big Bang, revealing a never-before-seen structure.

At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...

Structures known as "zippers" and "twisters" in the early universe may explain why dwarf galaxies tend to line up with each other, as well as hint at how dark matter operates in the universe. When you ...

New telescope instruments now reveal distant galaxies in detail, reshaping how astronomers map dark matter, star formation, and the early universe.

NASA’s Hubble finds Cloud‑9, a starless gas cloud dominated by dark matter. The first confirmed “failed galaxy” reveals hidden cosmic structures and new insights into galaxy formation.

Using the Subaru Telescope's wide-field camera, astronomers have discovered a previously unknown structure surrounding a tiny ...
