Uñallamacha: the blue-white star of Scorpius

blue-white · Scorpius · HD 155985

Uñallamacha is a blue-white star — the colour of the hottest, youngest suns in the constellation Scorpius, one of the few thousand stars bright enough to carry an officially recognised name. On a dark, clear night you can find it with your own eyes.

Most stars in the sky are anonymous points of light. Uñallamacha is not — it has held a name across generations of sky-watchers, which makes it a rare thing to attach a name of your own to.
