INTERACTIVE LAB
Where is Carina tonight?
Only the northern part of this constellation is seen from Türkiye, low on the southern horizon. The lab opens for Ankara on today’s date; switch the city to Antalya and then to Sydney and watch how the “Visible part” row and the chart change. The “Best night” button jumps to the best date (around 9 April).
MYTH, HISTORY AND OBSERVING
The keel of the Argonauts’ ship Argo; in 1756 Lacaille split Ptolemy’s huge constellation Argo Navis into three. Canopus, the second-brightest star in the sky, can be glimpsed from Türkiye only from the southernmost coasts, just above the horizon and only briefly. The vast Carina Nebula and the unstable supergiant Eta Carinae are here.

SOURCES
Position, visibility and best observing time were computed approximately for this page from the catalogue stars (Ankara, 39.9° N). The 88 constellations were adopted by the IAU in 1922; their boundaries were drawn by Eugène Delporte in 1930.
