DescriptionThe Stern of the great ship Argo was one of three sections when Lacaille divided the enormous ancient constellation Argo Navis in the 1750s. Puppis lies in one of the richest regions of the Milky Way and contains an extraordinary density of open star clusters. The brightest star, Naos (Zeta Puppis), is one of the hottest and most luminous stars known — a blue O-type supergiant about 1,090 light-years away with a surface temperature around 42,000 Kelvin, seven times hotter than the Sun, and roughly 220,000 times more luminous. Naos is also a runaway star, likely ejected from a binary system when its companion exploded as a supernova thousands of years ago.
