You could also take a screenshot at a higher resolution and then scale it down; most effective way to get rid of the aliasing (pixelation around the edge of the planet).
I've been really interested in the idea of an extraterrestrial civilisation going through the same discoveries and exploration that we have. These are basically just images that I imagine some might take during their exploration of space.
An alien version of Earthrise (their home planet rising over their moon as they orbit it shortly before landing):
Their space telescope snapping this image of a nearby pair of planets that are tidally locked and superheated:
A probe approaching the two Venus-like planets:
A lander taking an image of the surface of one of the planets, shortly before being crushed under atmospheric pressure and melted due to the extreme heat:
