The

Its story

Theta Crateris is a blue-white type B star glittering some 280 light-years away, in the cup that —so the myth tells— Apollo flung into the sky beside the Raven and the Hydra. It is a fast rotator, like many of its kind: it spins so quickly that its atmosphere bulges at the equator and traces a faint gaseous disc around itself. One of those stars that seem still and yet whirl like tops.
