Hot blue starIts story
31 Persei shines blue-white more than five hundred and sixty light-years away, within a young, hot Perseus. It belongs to the Perseus OB2 association, a cluster of massive stars still bound by their shared birth in a gas cloud. Its B-type atmosphere is one of the few places in the sky where the human eye can sense, without knowing it, the true blue of the hottest stars.
