The Horsehead Nebula consists of a cloud of ionized gas lit from within by young, hot stars; a dark cloud containing interstellar dust lies immediately in front. The dust absorbs the light from part of the ionized cloud. A portion of this dark cloud has a shape somewhat resembling a horse’s head. The nebula is located 1,300 light-years from the Sun.
The Horsehead Nebula is a prime target for many amateur astronomers, despite the difficulty many have viewing it. Upgrades in technology have made observations easier with inexpensive equipment, but it can still be a challenge to pick out of the sky. Glare from a nearby star makes it difficult to spot, as does its small size.
Since the images in this blog are relatively large and contain a lot of detail, if you are using a phone or a small tablet, you might want to consider returning sometime when you can use a computer with its larger screen.
