Astronomers say the Square Kilometre Array (SKA) may be able to detect magnetic fields on distant exoplanets. The work focuses on how planetary magnetism could help identify potentially Earth-like worlds beyond our solar system.
Recent exoplanet studies have moved beyond using a planet’s position in a star’s “habitable zone” as the sole indicator. Researchers note that some stars are more active than the Sun, meaning planets in their habitable zones can receive much higher levels of radiation than Earth does. In this context, a planet’s magnetic field becomes important because it can help shield an atmosphere from harmful particle and radiation effects.
Both outlets describe the same overall motivation and framing: magnetically protected planets may be better candidates for habitability assessment. They differ mainly in how they elaborate the background, but neither provides conflicting details about the premise or the role of SKA.
