Corona Australis
Southern Crown (Coronae Austrini)
Corona Australis, the Southern Crown, is a small but ancient constellation lying just south of Sagittarius. It has been recognized since antiquity as a circlet of stars forming a crown or wreath. Though faint, it lies in a beautiful region of the Milky Way and contains the Corona Australis molecular cloud, an active star-forming region.
📜 Mythology
Corona Australis was known to ancient Greek astronomers, though it was considered too far south for a proper myth. Some classical sources associate it with the crown that Dionysus placed among the stars after receiving it from his mother Semele. Others suggest it represents a laurel wreath awarded to a hero. Its resemblance to Corona Borealis (the Northern Crown) is deliberate - they are celestial counterparts representing crowns in opposite hemispheres.
