The Horsehead Nebula is one of the most beautiful natural spectacles in the Universe. Our only objection is that scientists obviously misnamed it — we don’t know about you, but we clearly see a duck in that main cloud rather than a horse head. The pink glow in the background is ionizing gas that is illuminated by a nearby star. East of the Duckhead Nebula there is a very active star formation region, containing very young stars with masses similar to our Sun.
