Four galaxies crowd the center of a collapsing structure 1.4 billion years after the Big Bang. Each one is churning out stars ...

Faint structures play a crucial role in cosmic development, and scientists are only just beginning to grasp their full extent ...

This enormous chain of hundreds of galaxies—a cosmic filament—is twisting through space 400 million light-years away ...

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international ...

What: New analyses using early observations from the European Space Agency’s Euclid mission examine how galaxy mergers ...

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The space observatory, named after a North Carolina native, ...

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 ...

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, ...

New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation.

The study of galaxies and their star formation processes remains a cornerstone of modern astrophysics. Galaxies are the fundamental building blocks of the Universe, each hosting a complex interplay of ...

Learn how dozens of galaxies may have merged into a giant galaxy shortly after the Big Bang.
