Astronomers have caught multiple massive galaxies in the act of merging about 4 billion years ago. This discovery, made possible by combining the power of the best ground- and space-based telescopes, ...

The galaxy's discovery challenges our understanding of how galaxies were formed in the early period after the Big Bang.

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 ...

Protogalaxies as seen by the James Webb Space Telescope (NASA via Courthouse News). (CN) — When astronomers started looking at new images of the deep universe obtained from the James Webb Space ...

A razor-thin cosmic filament is one of the largest rotating structures ever found, with implications for early galaxy ...

How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation has remained a puzzle for decades, but a University of Arizona-led ...

The James Webb Space Telescope's discovery of unusually bright and massive galaxies soon after the Big Bang has cast doubt on the standard model of galaxy evolution and bolstered a rival theory for ...

A spiral galaxy, shaped much like our Milky Way, has been found in an era when astronomers believed such well-formed galaxies ...

Scientists have found a remarkably small yet bright object from the early universe that doesn’t make sense in our existing models of how stars and galaxies formed, even our own Milky Way. That means ...

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.
