Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that ...

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 ...

On Oct. 11, 2022, NASA’s James Webb Space Telescope spent over 20 hours observing the long-studied Hubble Ultra Deep Field for the first time. The general observer program (GO 1963) focused on ...

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 ...

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open ...

Star chemistry reveals two spiral arms and a faint bridge in the Milky Way, offering a clearer view of hidden structure in ...

A study published in Astronomy & Astrophysics has identified four previously unknown primordial open cluster (OC) groups in the Milky Way. Open clusters, loose assemblies of stars born from the same ...

Star formation is an intricate process that transforms vast molecular clouds into newborn stars, often accompanied by the formation of circumstellar discs composed of gas and dust. These ...

This article delves into the discovery and classification of binary clusters, pairs of star clusters, which provide insights ...

TOI-1136, a dwarf star located more than 270 light years from Earth, is host to six confirmed exoplanets and a seventh as yet unconfirmed candidate. The system has provided a rich source of ...

A study published today in Astronomy & Astrophysics marks a significant milestone in our understanding of the formation and dynamical evolution of multiple stellar populations in globular clusters ...

Astronomers studying 3I/ATLAS, the third confirmed interstellar object ever recorded, say new data reveal that the comet ...
