Hot blue starIts story
τ Andromedae is a hot blue star more than seven hundred light-years away, set in the silhouette of the chained princess. Its cold, electric light travels from a distant point of the galactic arm, crossing vast regions of interstellar dust before reaching our telescopes. Its B spectral type marks it as a massive star with a short life and a likely catastrophic end.
