The north is at top. This is a huge emission nebula in Perseus constellation. It is a cloud of gas, mainly hydrogen, which glows due to the ionisation by radiation from a hot nearby star. The California Nebula is made glowing by the 4th magnitude star Menkib (Xi Persei, the bright blue star in center right). The nebula is named because recall the shape of the US state when viewed from the west. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory.
