 Mythology of Ara

Ara lies in the Milky Way, south of Scorpius. It is well to the south of the celestial equator but was known to the ancient Greeks, who visualized it as the altar on which their gods swore an oath of allegiance before challenging the Titans for control of the Universe. It is also depicted as the altar on which Centaurus is about to sacrifice Lupus, the wolf.

 Best Viewed Objects/Stars

NGC 6193

 An open cluster, consisting of a handful of stars scattered over an area half the apparent size of the full Moon. Its brightest star is of 6th magnitude, and the whole cluster is best seen with binoculars.

NGC 6397

 A large globular cluster, about two-thirds the apparent size of the full Moon and one of the closest to us, at slightly over 7,000 light-years away. It is just visible to the naked eye and easy to find with binoculars. The stars, less densely packed than in many globulars, form chains in the outer regions that can be seen with a moderate-sized telescope.
