Artist's Conception of Kappa Ceti (image) Harvard-Smithsonian Center for Astrophysics Share Print E-Mail Caption In this artist's illustration, the young Sun-like star Kappa Ceti is blotched with large starspots, a sign of its high level of magnetic activity. New research shows that its stellar wind is 50 times stronger than our Sun's. As a result, any Earth-like planet would need a magnetic field in order to protect its atmosphere and be habitable. The physical sizes of the star and planet and distance between them are not to scale. Credit M.
