Astronomers have discovered that planets can survive without stars, drifting as rogue or hypervelocity worlds. Some are flung into space by black holes, while others are displaced by gas giants. On some of these rogue worlds, the idea goes, there might be oceans beneath icy crusts, where life, at least life at a microbe level, could exist.
