Carina
Carina is visible in the far southern sky in the months around January. Visually, it is dominated by the star Canopus, the second brightest star in the sky.
It is also home to one of the sky’s most variable stars, η-Car, which in recent times has remained rather faint at mag 7–8, but in 1843 briefly rivalled Sirius in brightness at mag –1.5.
Until the eighteenth century, Carina was part of the much larger ancient constellation of Argo Navis, listed by Ptolemy among his 48 constellations in the second century. Argo Navis covered over 4% of the sky, an area 25% larger than the biggest modern constellation, Hydra.
In 1763, Nicolas Louis de Lacaille divided it up into three parts: Carina, Puppis and Vela. As a result of this relatively recent subdivision, the Bayer designations (α, β, γ, etc) are split between the stars of the three constellations.
In classical mythology, Argo Navis was the ship sailed by Jason and the Argonauts on their voyage to recover the golden fleece. Carina represents the ship’s keel.
In the Indian system Carina is known as ದೇವನೌಕಾ (Devanauka)
