The Ring Nebula, M57. Credit:PS1SC/Nigel Metcalfe
This month’s Pan-STARRS image of the Month is M57, the Ring Nebula. This is a planetary nebula, remains of the death-throws of a star of about the same mass as the Sun. The colour variations are caused by excited low density gas. Different colours indicate different elements or different levels of excitation. The dot in the centre is a white dwarf, the remnant of the now dead star which created the nebula.
