Hot blue star

Its story

23 Orionis is a hot blue B-type star more than 1,550 light-years away, set on the outskirts of one of the sky's most famous stellar nurseries —the Orion OB association, the birthplace of massive stars like its own. Its light departed around the year 470, as the Western Roman Empire was unraveling. It arrives now after crossing the faint interstellar dust that veils the whole Hunter.
