SKA May Detect Magnetic Fields on Distant Exoplanets

Studying exoplanets has provided astronomers with a plethora of insights regarding what characteristics need to be searched to find life beyond Earth. For the longest time, astronomers merely thought an exoplanet in a star’s habitable zone was a sufficient criterion for an Earth-like world. However, astronomers have learned that certain stars are more active than our Sun, resulting in exoplanets orbiting in the habitable zone being blasted with far more radiation than Earth could handle. In recent years, astronomers have recognized that a planet’s magnetic field, which shields the Earth from harmful radiation, could be a prime characteristic for identifying Earth-like worlds.
