We explore how moons stay bound to their planet during violent ejections into interstellar space, and how tides, radiogenic heat, and a dense CO2 atmosphere could keep oceans liquid—and life—alive without sunlight. Chemotrophic ecosystems at hydrothermal vents, aided by cosmic-ray chemistry, offer a path for life to originate and persist in darkness. If rogue planets outnumber stars, these starless worlds could be the galaxy’s most abundant habitable real estate.
