Recently I was playing with MidJourney and I did some planetary scenes under the light of a blue (O-type) star. I liked the results so much that I made them my current desktop wallpapers.
There’s a lot of nuance involved in getting MidJourney to give you exactly what you had in mind, but personally I love just seeing what it comes up with. If it’s not all that close to what I had in mind, that can be pretty cool too, because it provided something new.
All of these have an aspect ratio of 16:10 which make them great for your Mac. You can download the whole set here.
