Question Evolving a Militarized Mechanical Ecosystem
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 small colony from a small civilization supposed to do to defend itself? It needs all the resources it can ...

Question Giving a Planet Sunburn
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 the atmosphere over most of the planet significantly reduce the received radiation, but to have one spo...

Question Making a Planet Seem Uninhabitable
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 gates scattered across the galaxy by an unknown race. Each gate has access to thousands (at minimum) of oth...

Question Heavy metal planets in a globular cluster
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 metals, but still have notably less metallicity than our solar system, which almost entirely precludes an...

Question Massive planets around an old blue star
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, photoevaporating their atmospheres to ensure that they don't become gas giants. Unfortunately these types of stars...

Question Limiting volcanism to certain points on an exomoon
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 the surface rather than having them be spread all over the moon like Io's volcanos or exist all over tec...

Question Effects of a super-Jupiter collision in a planetary system
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 system's largest gas giant and then left the system. Planetary System The planetary system is quite young;...

Question How to make exomoon lightning storms
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-mass ice giant (the same ice giant mentioned in this question) in a system with unusual quantities of fluor...

Question Exoplanetary Review: Acid Rain
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 he's just guessing for most of this, especially the atmospheric makeup. The other planet is here Iyutha ...
