Gam

Its story

Gamma Sagittae inhabits the small Arrow, a tiny but perfectly recognisable asterism cutting across the summer Milky Way. It is the brightest of its constellation, an orange K-type giant whose light has been travelling for more than two and a half centuries: what arrives tonight set out while the United States Constitution was still being drafted. Its warm glow marks the very tip of the arrow that, in Greek myth, Heracles loosed at the Stymphalian Birds.
