Questions tagged [interstellar]
Used for questions asking about interstellar (non-nebula) issues other than planets and travel. This would include interstellar (or multi-stellar) civilization, communication, combat, and the contents of space between solar systems NOT relating to potentially habitable planets. For planets in the interstellar medium, use the interstellar-planets tag. For travel, use the interstellar-travel tag. Questions that involve nebula should use the nebula tag.
