Description

The horse's head is formed by cold dark dust clouds blocking the deep red glow of hydrogen ionized by the nearby star Sigma Orionis, while the “flame” is formed by cold dark filaments threading their way through the nearby bright orange emission nebula.

They are both close to us; the Flame Nebula is a mere 1,354 light years away, while the Horsehead is 1,500 light years away.
