A family portrait of the Andromeda galaxy and its orbiting dwarf satellites raises questions about how galaxies evolve.

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

Recent research has uncovered a barred spiral galaxy formed 11.5 billion years ago, making it one of the earliest known galaxies that contains a stellar bar. The research was supported by Yingjie ...

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

Astronomers have puzzled for decades over how massive elliptical galaxies appeared so early in cosmic history. The standard ...

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 ...

Long strands of glowing gas stretch behind a distant galaxy, dotted with pockets of newborn stars. The shape looks almost biological, like tentacles drifting through water.
