Radio Signals Detected from Earth-like Planet with Life-Sustaining Magnetic Field

Scientists have detected radio signals from YZ Ceti b, a rocky exoplanet located 12 light-years away from Earth, which suggests the presence of a magnetic field. This marks the first possible detection of a magnetic field on an exoplanet. Magnetic fields are crucial in creating habitable planets, as they protect them from energetic particles from a star that can strip away their atmosphere. Although YZ Ceti b is not habitable, this discovery offers a promising lead in identifying magnetic fields on Earth-like planets in other solar systems and advancing the search for potentially habitable worlds beyond our own.
