Xi-1

Hot blue star

Its story

Xi-1 Sagittarii is one of the most distant stars the unaided eye can reach: more than two thousand light-years away, its light began the journey when Rome was still a republic. It is a hot blue B-type beacon, embedded in the heart of the Milky Way, in the very direction where the galactic centre lies hidden. Its brilliance crosses one of the most densely populated regions of the sky, sown with clusters and nebulae that only the northern summer reveals in their full splendour.
