For those replying to this article with "imagine living there", please note that if life is a verdant, resilient and common as many of us hope it is, the universe might contain quite a number of insane places to live:
- Near the center of a galaxy, where stars are so closely packed together that the night sky is filled with bright lights, perhaps illuminating their world to what we experience around twilight, or even brighter.
- Far removed from the center of a galaxy, or even on a rogue star that has escaped its galaxy early on. Very few stars visible in the sky.
- Inside a 'thick' nebula, obscuring all other entities in the sky except for their own star and planets. Imagine an interstellar object like Oumuamua passing through and the complete perplexity of a civilization observing it and wondering where it could have come from.
- A double planet system.
- A system where the planet's orbit is highly elliptic, or where the precession of a tidally locked planet causes day/night cycles.
