Dark Nebulae |
The summer Milky Way brings spectacularly dense clouds of stars. But in many areas there are also dark regions. In the early 20th century, astronomer E.E. Barnard established that some of these are cold, dark clouds of obscuring gas rather than holes in the distribution of stars. His work culminated in the publication of a catalog of these dark areas, which have come to be known as Barnard objects.
