Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people

Cederblad 214 in Cepheus

By marzulloj at Tue, 10/20/2009 - 8:34pm

Three hour expousure in H alpha last night. Here hot OB stars associations light up this  molecular cloud, Cederblad 214. This is one of the largest molecular cloud complexes in the Milky Way.  Stellar winds and supernovae driven shock fronts produced by the hot OB stars of the association have expanded an immense 200 light year diameter shell of molecular gas which contacts the surrounding cold molecular cloud.
