Do Stars have a Pulse?

This picture contains thousands of stars that, from a distance, all look the same: like pretty little points of light. But on closer inspection they span many different colours, sizes and temperatures: from cool red dwarf stars to blisteringly hot blue supergiants! And while many spent most of their lives calmly burning hydrogen in their centres and shining with constant, unwavering light, others are far more active. The brand new class of stars that has just been discovered by astronomers in Japan fits into the second category!
