Abell 24 is a red-hued planetary nebula located in the constellation of Canis Minor. Despite its name, this type of nebula has nothing to do with planets. The term was coined by William Herschel in the 1780s, during a time of low-resolution astronomy, when it was very hard to differentiate nebulae from planets.
