ESOcast 76: uma vista polarizada de magnetismo estelar

Os telescópios do ESO estão a ser utilizados para procurar sinais subtis de campos magnéticos noutras estrelas e até mapear manchas estelares nas suas superfícies.Esta informação começa a revelar como e porque é que tantas estrelas, incluindo o nosso Sol, são magnéticas, e quais as implicações deste fenómeno na vida na Terra e noutros lados no Universo.
