A vast cloud of dust and gas within the Orion constellation, blocking light from the stars behind it.

What Is It?

The nebula's shape resembles the head and neck of a majestic horse.

Why "Horsehead"?

It lies about 1,500 light-years from Earth, a neighbor (cosmically speaking) to Orion's famous belt.

Where to Find It?

The Horsehead is best observed in infrared light, which can penetrate the obscuring dust.

The young, bright stars within the nebula erode the nebula’s shape, sculpting its iconic form.

Stellar Nursery

Strong stellar winds will eventually disperse the Horsehead Nebula, its shape ever-evolving.

Cosmic Change

Discovered in 1888 by Scottish astronomer Williamina Fleming, but gained widespread attention later.
