For generations, astronomers have catalogued thousands of worlds circling distant suns, yet the humbler question of whether those worlds themselves host moons remained unanswered. Now, a team using the Very Large Telescope in Chile has detected a Jupiter-mass body orbiting the brown dwarf CD-35 2722 B — a substellar object suspended between planet and star — marking the first uncontroversial evidence of a satellite around a companion world. The method is old, the target is novel, and the implication is quietly profound: the architecture of worlds within worlds may be far more common than our i
