Warm mid-August summer nights offer prime conditions for spotting three magnificent star clusters visible to northern-hemisphere skywatchers in the coming months. Star clusters are gravitationally ...

A trio of massive, young star clusters found embedded in a star cloud may shed light on the formation of super-star clusters and globular clusters. The discovery, made with images taken with 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 ...

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 ...

Galaxy AM 1054-325 has been distorted into an S-shape from a normal pancake-like spiral shape by the gravitational pull of a neighboring galaxy, seen in this Hubble Space Telescope image. A ...

A computational model of the early-to-present-day Universe predicts that some of the first stars formed in structures that challenge conventional classification. Read the paper: The emergence of ...

Star clusters are collections of thousands to millions of stars bound together by gravity — and many can be observed in the night sky with binoculars or a small telescope. One notable example is ω ...

New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed ...

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the ...
