You think they will have night side lights for other planets with multicell life to represent alien civilizations
Under Planets section.
Lights of the night side (hot planets, lava, cities)
Also as always
Anyway, I should note: as long as SE is a scientifically accurate Universe simulator, then one day it will implement ALL space objects and phenomenon that are known to modern astronomy. So you may not bother yourself with questions like "will SE one day have meteor rain implemented". I guarantee that it WILL.
Since intelligent life exists on Earth, it probably exists somewhere else and so that kind of plays into representing the universe we live in.
