Some people think it’s a fish-head. This colourful cosmic portrait actually highlights the contrasts between the luminescence of the gas and the opacity of the dust clouds in the boreal constellation of Cassiopeia. The colors of the nebula were calibrated from the palette used to render the Hubble Space Telescope images: blue for oxygen emissions, green for hydrogen emissions, and red for sulfur emissions. Not far from Perseus’ double cluster, IC 1795 is also close to IC 1805, the Heart Nebula, both of which are part of a complex of star-forming regions on the edge of a large molecular cloud. Located about 6000 light years from the solar system, this complex extends across the Perseus arm of our Galaxy, the Milky Way.
