Its story

Epsilon Persei shines some 638 light-years away, a hot blue B-type star that pulses with the restless rhythm of Beta Cephei variables. It anchors the body of Perseus, the hero fixed to the northern winter sky, where its cold fire shares the stage with Algol and Mirfak. A spectroscopic binary, its companion has never been resolved in a telescope —only inferred from the slow swing of its spectral lines.
