Hello!

Dark Nebula are clouds of interstellar matter, thin but widespread agglomerations of gas and dust. If they are large and massive enough they are frequently places of star formation, thus generating new associations or clusters of stars. Nebulae originate from large cosmic primordial clouds of gaseous matter in our Universe, leftover from its formation. Or they can come from enriched material ejected into interstellar space during the later life stages of the more massive stars. On cosmic timescales, nebulae undergo rapid changes and have only comparatively short lifetimes, so that those we observe are all young objects. Some of the stars near nebulae are often very massive and so hot that their high-energy radiation can excite the gas of the nebula to shine; such nebula is called emission nebula. If the stars are not hot enough, their light is reflected by the dust and can be seen as white or bluish reflection nebula. Some nebulae are only visible by the absorption of the light from objects behind them. They are distinguished from diffuse nebula mainly because they happen to be not illuminated by embedded or nearby stars. These are called dark nebula.



In 1927 Edward Emerson Barnard (1857 - 1923) published posthumously) a book titled "A Photographic Atlas of Selected Regions of the Milky Way". Barnard was a professor of astronomy at the University of Chicago Yerkes Observatory. As a pioneer in astrophotography, he cataloged a series of dark nebula of the Milky Way, giving them numerical designations, using the 10-inch (25-cm) Bruce wide-field telescope, built specially for him.

         

Through this work of studying the structure of the Milky Way, he discovered that certain dark regions of our galaxy are actually clouds of gas and dust that obscured the more distant stars in the background. His book is a list of 352 dark nebulas with finder charts and photographs.
