I've come up with a couple of exoplanets for a story, and have reached the limits of my knowledge. I've googled around, and I had a space enthusiast friend look at them, but he freely admits that h...

I have a terrestrial moon that I would like to have spectacular and frequent lightning storms. What atmospheric compositions and conditions could cause this? Tools The moon orbits a 21 earth-mas...
Split out from this question since it was too large. I'm designing an exoplanetary system that was the victim of a drive-by super-Jupiter ejected from a nearby supernova that crashed into the syst...
I have an exomoon that orbits close enough to its planet that it has notable geological activity. I would like to limit active volcanoes/geysers/lava lakes/etc. to at most, a couple dozen areas on ...
I read recently that metal-rich planetary systems around large (>5 solar masses) O- and B-type stars can form enormous solid planets (potentially bigger than Jupiter) relatively quickly, photoev...
Globular clusters are old, dense groups of stars that tend to have relatively few metals (in this case meaning any elements heavier than helium). Clusters near the galactic core tend to have more m...
How can I make it so that an otherwise colonizable planet (or moon) can (entirely naturally) seem uninhabitable from a certain point on its surface? Background: There are a series of immovable gat...
How can I make a colonizable planet/moon that receives intense UV/x-ray radiation on parts of its surface while receiving much less on the rest of it? The most obvious way of doing this is to have...
How could a civilization create a dangerous autonomous mechanical ecosystem that will not be overly dangerous to its creators? Militaries are expensive; military research doubly so. So what's a sm...
