Outer space in illustrations is full of stars, planets, galaxies, moons, asteroids, spaceships, wormholes, and the occasional elder god on his way to work. So I've gathered a variety of tutorials and tips for drawing everything cosmic for this post.
Don't worry about the specific app or medium used to create these drawings. Observe and learn the technique and you can recreate it on anything. Watching a tutorial about an app you don't have? You can probably find an equivalent brush in whatever you're using. Same goes for digitally emulating traditional art mediums. Whatever app you're in, chances are, there's a brush for that. The technique and philosophy behind any piece of art is universal and translating it with your chosen tool is what makes your art yours.
I've combed the internet to find some of the most useful video tutorials out there on creating space artwork. The mediums are different, but all could be adapted to your own needs and tools.
The videos below show how to make a flowing space scene using your fingers in the app Paper, but the techniques are simple enough to be able to apply to any digitally drawn outer space scene so don't be afraid to try it out.
Now let's learn to make an outer space scene with planets and stars and even an asteroid with Alphonso Dunn.
Every solar system needs a sun and a moon or two. Here's a digitally drawn sun and a moon drawn in pastel.
Okay, we've got our space background, let's try out some spaceships to travel our little piece of the universe.
Here's a couple of valuable techniques for drawing spacecraft. The first is using a 1-point perspective to give your ship a sense of depth and distance. The second is using a copy / paste / flip technique (symmetry if your app has the ability) to give your ship a nice sense of symmetrical construction.
Here's a small gallery of some great interstellar illustrators of the 20th century to inspire you and your own extrasolar artwork.
