Strange winds reveal strongest hints yet of magnetic activity in exoplanets
A team of astronomers has found the strongest evidence yet that some planets outside our Solar System may be magnetic. Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and the Gemini North telescope, the researchers measured wind speeds on seven very hot, Jupiter-like exoplanets. The observations revealed that the winds on these planets are most likely governed by magnetic fields, providing the first robust measurement of magnetism on planets outside the Solar System.
