High Quality Content by WIKIPEDIA articles! Volans is a constellation in the southern sky. It represents a flying fish; its name is a shortened form of its original name, Piscis Volans. Volans was one of twelve constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman and it first appeared on a 35-cm diameter celestial globe published in 1597 (or 1598) in Amsterdam by Plancius with Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. There are two double stars within the constellation which can be observed using a small telescope, Gamma Vol and Epsilon Vol, along with two galaxies which may be more difficult to see clearly; NGC 2442 and NGC 2434. The magnitude of the Gamma Vol stars are fourth and sixth, and that of Epsilon Vol (known as Nolans Volan) are fourth and eighth.
