Hot blue starIts story
Omicron Hydrae is a hot blue B-type star buried in the winding body of Hydra, the largest constellation in the sky. About 449 light-years away, it shines with the concentrated energy of an atmosphere far hotter than the Sun’s, lost among the coils of the greatest of celestial serpents. Hydra spans so much sky that it takes almost seven hours to cross the meridian end to end: throughout that long passage, Omicron rises and sets like a slow blue heartbeat along the monster’s body.
