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 discovery of the universe’s oldest stars, identified within our own Milky Way galaxy, marks a significant leap forward in our understanding of cosmic history. These ancient stars, formed shortly ...

What can fast-spinning stars known as “blue lurkers” teach us about star formation and evolution? This is what a recent study being presented at the 245th American Astronomical Society meeting hopes ...

Professor Woong-bae Zee of the College of Liberal Studies at Sejong University has revealed that a galaxy does not possess only a single evolutionary pathway; instead, depending on the nature of its ...

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 ...

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to Type II supernova explosions.

Astronomers used RR Lyrae stars to trace the early Milky Way, revealing a rapid formation of its halo and disk, with chemical patterns similar to Andromeda.

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 ...

Astronomers have reported observations of a rare star system consisting of one star orbiting a system of three more tightly ...

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 ...

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 ...
