East of Antares and
towards the center of our galaxy, the Milky Way, there are dark spots that
extend over fields full of stars.
Cataloged in the early
twentieth century by astronomer EE Barnard, these dark interstellar dust clouds
include B59, B72, B77 and B78, which are seen in silhouette against the starry
background.
Their combined form
suggests the cannula and the bowl of a pipe, hence the popular name of the Pipe
Nebula. This deep and extensive image was recorded after nearly 24 hours of
exposure time of very dark skies of Chile's Atacama Desert. It covers an area
of 10 by 10 degrees in the constellation Ophiuchus.
The Pipe Nebula complex
is part of the Ophiuchus dark clouds at a distance of about 450 light years.
The dense cores of gas and dust inside the Pipe Nebula are collapsing to form
stars.
