East of Antares |
| Explanation |
East of Antares [ http://antwrp.gsfc.nasa.gov/apod/ap020526.html ], dark markings seem to sprawl through the crowded star fields toward the center of our Milky Way Galaxy. Cataloged in [ http://adsabs.harvard.edu/cgi-bin/ bib_query?1919ApJ....49....1B ] the early 20th century by astronomer E. E. Barnard [ http://astro.uchicago.edu/yerkes/virtualmuseum/ Barnardfull.html ], the obscuring interstellar dust clouds include [ http://www.saguaroastro.org/content/ Best-of-Barnards-Dark-Nebulae.htm ] B72 [ http://antwrp.gsfc.nasa.gov/apod/ap050521.html ], B77, B78, and B59, seen in silhouette [ http://antwrp.gsfc.nasa.gov/apod/ap001229.html ] against the starry background. Here, their combined shape suggests smoke rising from a pipe, and so the dark nebula's popular name is the Pipe Nebula. This gorgeous and expansive view [ http://panther-observatory.com/gallery/deepsky/doc/ Pipe_200mm.htm ] was recorded in very dark skies over Hakos, Namibia [ http://www.fallingrain.com/world/WA/40/Hakos.html ]. It covers a full 10 by 7 degree field in the pronounceable [ http://www.astronomyclub.org/learn/Say_What.htm ] constellation Ophiuchus. |
