Another drawing on photoshop I created all from scratch, earlier than the one below!
In this drawing I as well used circular marquee a lot and the gaussian effect. To create the nebula in the top left i used A LOT of brushes and other effects such as Color dodge and more. I used the layer settings as well to tweak up the glowing effects of everything. And finally finished it off with a solar flare shining behind the planet to give it its sunrise effect.
