DescriptionThe Northern Crown is one of the most elegant small constellations — a perfect arc of stars forming a delicate tiara shape that has enchanted observers for millennia. In Greek myth it is the golden crown given to Ariadne by Dionysus as a wedding gift after Theseus abandoned her on the island of Naxos; when she died Dionysus threw the crown into the sky where it became a circle of stars. The constellation is home to one of the most remarkable variable stars — R Coronae Borealis, which normally shines at magnitude 6 but sporadically and unpredictably plunges to magnitude 14 as clouds of carbon soot condense around it, appearing to mysteriously 'disappear' from the sky without warning.
