Crown, are two small constellations among the 48 listed by the 2nd-
century astronomer Ptolemy. Corona Borealis, which generally represented
the crown given by the god Dionysus to the Cretan princess Ariadne, is
in the Northern Celestial Hemisphere, while Corona Australis, associated
with Sagittarius or Centaurus, is in the Southern. Corona Borealis
boasts the highly variable stars R and T Coronae Borealis and the huge
Corona Borealis Supercluster. Corona Australis, lying alongside the
plane of the Milky Way, hosts Epsilon Coronae Australis, the brightest
example of a W Ursae Majoris variable in the southern sky. It also
contains one of the closest star-forming regions to our Solar System,
about 430 light years away—a dusty dark nebula known as the Corona
Australis Molecular Cloud, with stars at the earliest stages of their
lifespan.
