Mu

Its story

Mu Hydrae burns with an orange glow more than two hundred light-years away, in the long middle stretch of Hydra. It is a K-type giant that has left behind its era of stable fusion and now swells its outer envelope while exchanging the white of its youth for this mature amber tone. Every photon reaching the human eye tonight set out around the time Newton was publishing his Principia, and has travelled more than two centuries with nothing to interrupt it but interstellar dust.
