NGC 1514 was discovered by William Herschel on November 13th 1790 describing it "A most singular phoenomenoa" and forcing him to rethink his ideas on the construction of the heavens. Up until this point Herschel was convinced that all nebulae consisted of masses of stars to remote to resolve, but now here was a single star surrounded by what he termed "a faint luminous atmosphere" and would go on to conclude "Our judgement I may venture to say, will be, that the nebulosity about the star is not of a starry nature".
It has since been conjectured that the nebula in fact envelops a tightly orbiting double star with a period of up to 10 days. Gas is presumably expanding away from the larger star of the pair.
