The Interstellar Clouds of Orion
Explanation: The constellation of Orion is much more than three stars in a row. It is a direction in space that is
rich with impressive nebulas. To better appreciate this well-known swath of sky, a new
long exposure image was taken over several clear nights in January, February and March. After 23 hours of camera time and untold hours of image processing, the featured collage in the light of
hydrogen,
oxygen, and
sulfur was produced spanning over 40 times the
angular diameter of
the Moon. Of the many interesting details that have become visible, one that particularly draws the eye is
Barnard's Loop, the bright red orange arc just to the right of the image center. The Rosette Nebula is
not the giant orange nebula just to the left of the image center -- that is larger but lesser known nebula known as the
Meissa Ring. The
Rosette Nebula is visible, though: it is the bright orange, blue and white nebula near the image bottom. The bright orange star just left of the frame center is
Betelgeuse, while the bright blue star on the upper right is
Rigel. About those
famous three stars that cross the belt of
Orion the Hunter -- in this busy frame they can be hard to locate, but a
discerning eye will find them just to the right of the image center.
