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 ...

Astronomers have recently uncovered an extraordinary star, SDSS J0715-7334, which may be the most “pristine” object ever discovered. Located in the halo of the Large Magellanic Cloud, this star offers ...

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 ...

Discover seven unusual galaxies defying scientific predictions, from impossibly bright early universe objects to astrophysics ...

How do stars form and evolve inside globular clusters? This is what a recent study published in Astronomy & Astrophysics hopes to address as an international team of researchers conducted a ...

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 ...

One and a half billion years ago the small, inconspicuous galaxy Messier 82 (M82) almost smashed into its large, massive neighbour galaxy Messier 81 (M81), causing a frenzy of star formation. New ...

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 ...

Researchers interrogated the 'sounds' of a cluster of stars within the Milky Way, uncovering a new technique for astrophysicists to probe the universe and learn more about its evolution. A new study ...
