In the Southern Sky, new constellations were often created from about the 15th century by voyagers who began journeying south of the Equator.European countries like England, France, the Netherlands, German or Italian states, etc., often supported and popularised their own constellation outlines.[3] Nearly all former or defunct constellations differ in their designated boundaries inasmuch as they have outlines that do not follow the exact lines of right ascension and declination.Due to its large size, it was split into three constellations by Nicolas Louis de Lacaille: Carina (the keel), Puppis (the poop deck), and Vela (the sails).[5] The new constellations were introduced in the 1763 star catalog Coelum Australe Stelliferum, which was published soon after de Lacaille's death.
