Lam

Its story

Lambda Cephei is a blue O-type supergiant, one of the hottest and most luminous stars visible to the naked eye, set almost two thousand light-years away. It is also a famous runaway, ejected from its parent association and now ploughing through the interstellar medium so fast that its stellar wind compresses the surrounding gas into a bow shock. It lives in a hurry and will die young, in a supernova explosion.
