The differences in location between open and globular star clusters result from the interplay between gravity and rotational motion. This rotational motion is called angular momentum, and is a ...
the constellation Orion with the Orion Nebula Cluster as the central “star” in the sword of Orion, the Pleiades and the Hyades. All three open clusters are highlighted by large yellow circles. Orion ...
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 Orion Nebula, the Pleiades and the Hyades open clusters could represent the different phases of star clusters: baby, ...
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 ...
Researchers from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences have made significant progress in understanding how three-dimensional (3D) layered structures form ...
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 ...
