Variable starWhat is HIP 76957
In the austral crown of Boötes lives a variable B-type star, blue-white and hot, whose brightness fluctuates with the inner pulse of its atmosphere. Its 299 light-years align with the founding era of Saint Petersburg under Peter the Great around 1727. Every flicker around magnitude 5.48 repeats a heartbeat emitted in the heart of the Russian Enlightenment.
