Variable star

Its story

104 Herculis is a variable M-type red giant 545 light-years away, set within the torso of the Hero. Its light is not steady —it pulses gently, as if breathing slowly on timescales that humble the human calendar. The deep red of its surface, far cooler than the Sun's, betrays a star in the final great chapter of its biography.
