Its story

It glitters white in Triangulum Australe, the small triangle of the southern sky, about 170 light years away. Its light set out around 1856, when Pasteur was laying the foundations of modern microbiology and Bessemer was patenting the process that would revolutionise steelmaking. A-type, somewhat hotter than the Sun, it radiates a pure white, almost like lit porcelain. A young, elegant star closing one of the most symmetrical figures of the austral sky.
