California nebula (NGC 1499),optical image. This is an emission nebula,a cloud of gas that glows due to the ionisation of the hydrogen it contains by radiation from a hot star nearby. In this case,the star responsible is Menkib (Xi Persei,lower right). The nebula is named for its resemblance to the US state when viewed from the side. Rotate this image 90 degrees anticlockwise to see the resemblance | |
