Variable star

Its story

A blue B-class variable in Puppis, 909 light-years away. The light we see tonight set out around 1117, when Peter Abelard was lecturing in Paris and the first stones of the future Notre-Dame cathedral were still waiting in the quarry. Its brightness oscillates slowly—it breathes, as many massive B-stars do in their slow internal adjustment.
