Star clouds are large groups of many stars within a galaxy, spread over very many light-years of space. The stars appear closely packed, but are not usually part of any structure.[1] Within the Milky Way, star clouds show as gaps around dust clouds of the Great Rift, allowing deep views along our particular line of sight.[2] Star clouds have also been identified in other nearby galaxies.[3] Examples of star clouds include the Large Sagittarius Star Cloud, Small Sagittarius Star Cloud, Scutum Star Cloud, Cygnus Star Cloud, Norma Star Cloud, and NGC 206.
Despite their names, the Magellanic Clouds are usually described as irregular galaxies, thus are not star clouds by the above criteria.
our views of star clouds are highly dependent upon perspective.
