Hot blue starIts story
More than twenty-six hundred light years separate this blue B-type giant from the earthbound observer. It dwells in the southern Altar constellation and its light departed when Babylon was falling to Cyrus the Great. What we see is the ancient echo of a vast, hot star, several dozen times more massive than the Sun and thousands of times more luminous.
