An unusual collection of stars may represent the remnants of a dwarf galaxy that the Milky Way devoured about 10 billion years ago. Astronomers have dubbed the ancient galaxy Loki, after the Norse god ...

Astronomers have gained insights into star formation by capturing the first spatially resolved detection of protostellar outflows and jets in the Milky Way's outer region. The research is published in ...

The Sloan Digital Sky Survey V (SDSS-V) has announced its 20th public data release (DR20), delivering a dramatic expansion of ...

Researchers combined deep learning with high-resolution physics to create the first Milky Way model that tracks over 100 billion stars individually. Their AI learned how gas behaves after supernovae, ...

Chinese astronomers have discovered that the Milky Way is not a simple, smoothly warped disk, but contains widespread "wrinkle-like" structures resembling ripples on a water surface, providing new ...
