Sig

Its story

Sigma Andromedae shines white at 135 light-years, an A-type star anchored to the silhouette of the chained princess. Its atmosphere, several thousand degrees hotter than the Sun's, gives it that crisp, almost surgical hue typical of young blue-white stars. When the light we see tonight first set out across interstellar space, Mozart had not yet written his last symphony and steam engines were beginning their slow conquest of Europe.
