Editing Vela (constellation) (section)

==History==
[[Argo Navis]] was one of the 48 classical constellations listed by the 2nd-century astronomer [[Ptolemy]], and represented the ship ''[[Argo]]'', used by [[Jason]] and the [[Argonauts]] on their quest for the [[Golden Fleece]] in [[Greek mythology]]. German cartographer [[Johann Bayer]] depicted the constellation on his  ''[[Uranometria]]'' of 1603, and gave the stars [[Bayer designation]]s from Alpha to Omega. However, his chart was inaccurate as the constellation was not fully visible from the Northern Hemisphere.<ref name=wagman>{{cite book  | last = Wagman  | first = Morton  | year = 2003  | title = Lost Stars: Lost, Missing and Troublesome Stars from the Catalogues of Johannes Bayer, Nicholas Louis de Lacaille, John Flamsteed, and Sundry Others  | publisher = The McDonald & Woodward Publishing Company  | location = Blacksburg, [[Virginia|VA]]  | isbn = 978-0-939923-78-6 |pages=83, 315–19}}</ref>

Argo was more accurately charted and subdivided in 1752 by the French astronomer [[Nicolas Louis de Lacaille]], forming Carina (the [[keel]]), Vela (the sails), and Puppis (the [[poop deck]]). Despite the division, Lacaille kept Argo's [[Bayer designation]]s. Therefore, Carina has the Alpha, Beta and Epsilon originally assigned to Argo Navis, while Vela's brightest stars are Gamma and Delta, Puppis has Zeta as its brightest star, and so on.<ref name=wagman/>
