Scientists have unveiled plans for a revolutionary telescope system that could finally answer one of astronomy's biggest questions: do moons orbit planets beyond our solar system?

Using a kilometric baseline interferometer—technology far more powerful than current methods—researchers believe they can detect the tiny wobbles of gas giant planets caused by orbiting moons.

This cutting-edge approach could spot Earth-sized exomoons up to 652 light years away, particularly around planets in colder orbits where tidal heating might create surprisingly habitable environments. While the multi-billion-dollar concept remains theoretical, it represents our best shot yet at discovering alien moons and expanding the search for life beyond Earth.
