Recent research led by David Dahlbüdding at the Max Planck Institute suggests that moons orbiting free-floating exoplanets could potentially support life.
The key factor for habitability is the presence of thick, hydrogen-dominated atmospheres, which would enable these moons to retain heat generated by tidal forces within their interiors.
This finding has significant implications for our understanding of celestial bodies outside traditional planetary systems and their potential for hosting life.
