Omi

Its story

Omicron Andromedae, also catalogued as 1 Andromedae, is a blue giant about 687 light-years away, set in the chained silhouette of the mythological princess. It belongs to the Be class: spinning so violently that a ring of glowing hydrogen escapes from its equator, causing the faintest of slow flickers across centuries. The light reaching us tonight left during the European Middle Ages, long before any telescope could pick out the red signature of hydrogen in its spectrum.
