Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

Scientists find strong evidence that magnetic fields shape the weather on distant exoplanets for the first time.

One of Earth's defining features is its magnetic field. It forms a protective shield against high-energy particles ejected by the Sun and thus arguably has provided life with a safer place to grow ...

Magnetic fields are a key factor in the evolution of planets and their atmospheres, but they are still poorly constrained for exoplanets owing to limited direct observations. Ultra-hot Jupiters ...
