Its story

30 Persei is a hot blue B-type star in Perseus, the hero who beheaded Medusa and rescued Andromeda. At 731 light-years away, its surface comfortably exceeds twenty thousand kelvin: it gives off a blue-white light and so much ultraviolet radiation that it overturns any intuition shaped by the Sun. Its glow travels from the era when the gothic was only being born in the great cathedrals of the Île-de-France.
