Astronomers using the James Webb Space Telescope have identified emerging young star clusters still breaking free from their dusty birth clouds in the nearby spiral galaxy NGC 628. A preprint posted ...

Astronomers have discovered the first pairs of white dwarf and main sequence stars -- 'dead' remnants and 'living' stars -- in young star clusters. This breakthrough offers new insights on an extreme ...

Greetings stargazers. While gazing at stars is fun, gazing at groups of stars is even more fun. The more the merrier. There ...

Massive young star clusters blow away their birth clouds in roughly 5 million years, not the 7 to 8 million years that ...

This is a tale of rediscovery. I have been an astronomer for more than half a century. My current observing concentrates on showcase nebulae and galaxies or the pursuit of fine lunar detail. But ...

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide ...

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 ...

The Hubble and James Webb Space Telescopes have revealed thousands of young star clusters emerging from their birth clouds. The observations, published in Nature Astronomy, show that more massive ...

Globular star clusters are huge balls of thousands of stars that orbit most galaxies. They are among the oldest known stellar systems in the Universe and have survived through almost the entire span ...
