Astronomy Picture of the Day

                         Astronomy Picture of the Day

    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: The constellation of Orion is much more than three stars in a
row. It is a direction in space that is rich [4]  with impressive nebulas. To
better appreciate this well-known swath of sky, a new long exposure image [5]
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 [6] , oxygen [7] , and sulfur [8] was
produced spanning over 40 times the angular diameter [9]  of the Moon [10] .
Of the many interesting details that have become visible, one that
particularly draws the eye is Barnard's Loop [11] , 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 [12] . The Rosette Nebula [13]
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 [14] , while the bright blue star on the upper right is Rigel [15]
. About those famous three stars [16]  that cross the belt of Orion the Hunter
[17]  -- in this busy frame they can be hard to locate, but a discerning eye
[18] will find them just to the right of the image center.
