Variable star

Its story

A blue variable on the sting of Scorpius. Pulsating B-type stars like this one beat because their atmosphere never settles into equilibrium between gravity and radiation pressure. At 555 light-years, its light left around the year Cortés reached Tenochtitlán and two worlds first set eyes on one another.
