Psi

Variable star

Its story

Psi Persei is a hot blue-white B-type star nearly six hundred light-years away, a probable member of the Per OB2 association, a brotherhood of young, massive suns born from the same gas cocoon. It is also variable: it spins so quickly on its axis that it casts off an equatorial disk of glowing gas whose brightness flickers with time. A restless star in full youth, set in the mythological heart of Perseus.
