Hot blue star

Its story

Segin caps one end of Cassiopeia's W, that unmistakable silhouette wheeling around the northern celestial pole. It is a hot blue star 412 light-years away, young in cosmic terms despite the great distance. Its light set out around the time of the first telescopes peering at the sky, when Galileo was sketching by hand the phases of Venus and the indistinct rings of Saturn.
