Its story

It looks out in the direction of Perseus, yet truly belongs to an extremely distant satellite galaxy, more than three hundred thousand light-years away. Its white light, proper to A-class stars, set out long before the rise of Homo sapiens —when no human eye yet existed to look at it. It is a variable whose brightness shifts slowly, and its true luminosity outshines the Sun by orders of magnitude. It offers a rare gift: contemplating an almost extragalactic star as a faint point in our own sky.
