Ups

Its story

Upsilon Coronae Borealis is a white type-A star some 667 light-years away, in the Northern Crown —that small semicircle of stars Greek myth identified with the diadem of Ariadne, cast into the sky by Dionysus. Its light set out towards us in the fourteenth century, when Europe was traversing the Black Death and astronomy was still inseparable from horoscope and liturgical calendar.
