Not only is the constellation Orion easily recognisable, it also contains many deep-sky objects, and thus attracts amateur astrophotographers'cameras. This time, we will introduce to you a nebula with an interesting shape! Let's look at the dark nebula in this photo. What does it look like?

That's right. It's called the Horsehead Nebula. It is a dark nebula lying about 1,400 light years away and is made up of dark interstellar gases and dust. Normally, in order to see this kind of nebula, we need to rely on the light source behind it. The red glow of the emission nebula IC434 at the back of the Horsehead Nebula marks the shape of a horse's head for this dark nebula.

The Horsehead Nebula is located near Alnitak, one of the stars that represent the Orion's belt. However, the nebula is very dim, it can only be seen with an astronomical telescope. This photo is the first light image of the SPECULOOS Southern Observatory after its establishment. There are also numerous spectacular photos of this nebula which are taken by amateur astrophotographers around the world. Let's try to find them out on the internet.
