IC 1871


IC1871 is a formation of gas and dust located in the much larger Soul Nebula.  It lies in the constellation Cassiopeia at an estimated distance of 6,500 light-years from the Earth.  Like clouds in our Earthly skies, the gas and dust in celestial nebulae often resemble familiar objects.  The image above is centered on a prominent “mountainous” feature in IC1871.
