The distinct spatial distributions of open and globular star clusters in spiral galaxies are a consequence of the interplay between gravity and conserved angular momentum, which facilitates the ...

This composite image was weeks in the making, as Horálek’s two "crossings" happened months apart. Mars traced its path ...

You'll find this terrific open cluster midway between 5th-magnitude Sigma Cassiopeiae and 6th-magnitude Rho Cas. This group ...

Beehive cluster, a group of 1,000 stars, will be visible to stargazers in January. How to see it, what’s visible to naked eye ...

The sun wanders the Milky Way alone; our star orbits the galaxy’s distant center without any stellar siblings. The solar ...

Hubble continues to deliver gorgeous images of the universe. One of the latest images the space telescope has captured is that of an open star cluster called NGC 2002. This cluster is located around ...

The center of the new image is dominated by a sparkling cluster of stars. The open star cluster NGC 2002 is situated in the Large Magellanic Cloud, a satellite galaxy of the Milky Way with several ...

Mid-winter in the Northern Hemisphere is a great time to catch up on some seldom-observed open star clusters. This week’s sextet lies within the boundaries of the constellation Canis Major the Great ...

Modifying gravity: Pavel Kroupa and colleagues have shown that Modified Newtonian Dynamics does a good job at describing the properties of open clusters of stars. (Courtesy: Volker Lannert/University ...

BERKELEY — A detailed survey of stars in the Orion Nebula has found that fewer than 10 percent have enough surrounding dust to make Jupiter-sized planets, according to a report by astronomers at the ...

The European Southern Observatory (ESO)has released a colossal 615 megapixel visible light image of astunning collection of bright young stars that make up the Messier 18open cluster. By observing the ...
