Hot blue star

Its story

Kaus Australis marks the lower part of the archer's bow in Sagittarius, the 'southern bow' aimed straight at the galactic heart. It is a hot, young blue star, fierce enough to cut through the dense band of the Milky Way behind it. Its light set out about 143 years ago, when the first transatlantic telegraph cables were still being laid.
