Its story

Over the long body of Hydra shines an F-class star, yellow-white and somewhat hotter than the Sun, lying a little over a hundred light-years away. The light that now defines it set out as Europe was sinking into the First World War and the first aeroplanes were timidly crossing the sky. Its pearly, almost metallic tone marks that stellar frontier between the Sun's yellow and the cooler white of Sirius.
