Description

About it...

The Horsehead Nebula is a Dark Nebula, silhouetted against IC434, a bright emission nébula, discovered by William Herschel.

The swirling clouds of gas and dark dust are lit by a pinkish glow of hydrogen gas located behind the nebula and ionized by the nearby bright star Sigma Orionis.

Sigma Orionis, which is in fact a five-star system, illuminates the entire region.

The jutting pillar that forms the Horsehead has a high density of helium and hydrogen
