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 ...

The Milky Way is at least 100,000 light-years across, but the new results suggest that the galaxy's star formation takes ...

Astronomers have observed a massive and extremely active barred spiral galaxy in the early Universe and found that it has important similarities and differences with modern galaxies. This improves our ...

The older stars migrated out from the galactic center, leaving the younger ones inside.

How can timing influence planetary formation and evolution? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of researchers investigated the ...

These three galaxy images from the AEGIS survey show a range of galaxy types: a disk-like spiral galaxy (top), a cloud-like elliptical galaxy (middle), and an irregular galaxy resulting from a ...

The combination of theoretical models and empirical data provides a new perspective for understanding the complex interactions between young stars and their environments. A study led by Paolo Padoan, ...

A series of new studies have uncovered fresh insights into the Milky Way’s structure, star formation, and early history. Researchers identified a self-regulating process controlling star masses in ...

Scientists have uncovered the true boundary of the Milky Way’s star-forming region using stellar “age mapping.” They found a ...

To understand how the universe was formed and how we got here, ancient stars are some of the best objects to study — yet astronomers know surprisingly little about the conditions in which they were ...

Abstract : Weighing in at 1042 kilograms and measuring 1021 meters across, galaxies are perhaps the most awe-inspiring objects known to mankind. They are also the only places in an otherwise dark and ...
