NGC 1514

NGC 1514 Observation data (Epoch J2000) Right ascension 04h 09m 16.984s Declination +30° 46' 33.47? Distance ~600ly (~190pc) Apparent magnitude (V) 9.43 Apparent dimensions (V) 2'.2 Constellation Taurus Physical characteristics See also: Planetary nebula, Lists of nebulae NGC 1514 is a planetary nebula that was discovered by William Herschel on November 13, 1790, describing it "A most singular phaenomenon" 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 too remote to resolve, but now here was a single star "surrounded with a faintly luminous atmosphere." He went 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.NGC 1514 is also known as Crystal Ball Nebula.
