... Explanation : The dark spots in the above picture are not photographic defects but an unusual type of interstellar cloud known as a Bokglobule . ...
... One hypothesis holds that the Cone Nebula is formed by wind particles from an energetic source blowing past the BokGlobule at the head of the cone . ...
... Recent observations of dust -darkened BokGlobule BHR 71, however, show evidence for two young stars forming deep in the cloud, likely close enough to form a binary . ...
... Cataloged as HH (Herbig-Haro) 46/47 the infrared source is lodged within a dark nebula or Bokglobule - near the lower right corner of the dark nebula in the optical inset - that is largely opaque when viewed in visible light. ...
... One hypothesis holds that the Cone Nebula is formed by wind particles from an energetic source blowing past the BokGlobule at the head of the cone . ...
... The dark shape is a dense gas and dust cloud, or Bokglobule , seen in silhouette against the bright nebula, and likely a site of future star formation. ...
... The dust cloud NGC 281, dubbed the Pacman nebula because of its overall shape , is classified as a dense BokGlobule that lies about 10,000 light years distant. ...
