The-1

Hot blue star

Its story

Theta-1 Orionis C is the dominant star of the Trapezium, the cluster of young suns that lights the heart of the Orion Nebula. Its brutal ultraviolet radiation sculpts the gas clouds around it and drives the fluorescence we see in every photograph of M42. It is one of the hottest stars in the sky reachable by the naked eye —the visible engine of the most famous stellar nursery.
