Its story

In Carina, the keel of the ancient ship Argo, shines a white A-type star, hotter and more luminous than the Sun. Its light took some 267 years to reach us: it set out around 1758, just as Halley had predicted the return of the comet that now bears his name and the Enlightenment was changing the way of looking at the sky. A clean spark, swift on cosmic scales, reinforces the southern keel.
