Description:  This object is an emission nebula and open cluster.  This also is an area of active star formation.  The long finger-shaped objects in the the image are massive columns of cold gas that extend from a vast cloud of molecular hydrogen.  Inside these light-years-long columns the interstellar gas is dense enough to collapse under its own weight and is in the process of forming new stars.
