The Dumbbell Nebula

M27 is a planetary nebula located around 1250 ly away in the constellation of Vulpecula. It shines at magnitude 7.5 meaning it is visible in binoculars on a dark, clear night.
The term planetary nebula comes from times when optical assistance was insufficient to distinguish this type of object from a distant planet. They are formed when a red giant star runs out of nuclear fuel; the star's outer layers are pushed out into space and the central star becomes a white dwarf. The ultra-violet radiation from this star illuminates the remnants of the star.
