The Andromeda galaxy has dramatically reduced its rate of star formation in recent millions of years, and astronomers have ...

Star formation in the galaxy has been on the decline for the past 500 million years.

A galaxy simulation shows that nuclear star clusters and nuclear stellar disks can grow together as a stellar bar funnels gas ...

Astronomers found that star clusters do not always form the same balance of small and large stars, challenging a long-standing assumption used to measure galaxies. Gaia data show that a key dividing ...

Researchers from Kyushu University have discovered that diffuse gas surrounding dense filaments in a nearby stellar nursery ...

Andromeda is one of the only galaxies you can see without a telescope, provided you find a stretch of sky dark enough. It's ...

For decades, astronomers lumped brown dwarfs into a single category defined by mass alone—too big to be classified as planets but too small to become stars. However, this definition ignores the two ...

The findings could help solve the mystery of how the first stars formed. The roughly four-billion-year-old system consists of a black hole and two orbiting stars—a configuration that's never been seen ...

This Collection features original research on the mechanisms driving star formation, the lifecycle of various stellar types, and the complex interactions between stars and their environments. The ...
