A team of astronomers looking at galaxies in the universe’s distant past have discovered nine young, compact galaxies, each weighing in at 200 billion times the mass of the Sun. Imagine receiving an ...

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.

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 ...
