This computer model shows the magnetic field lines of the star Kappa Ceti as gray lines looping out from the star's surface. This young, Sun-like star generates a stellar wind 50 times stronger than our Sun's. As a result, any potentially habitable planet would need a magnetic field to protect its atmosphere.
