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 GeminiNorth telescope, the researchers measured wind speeds on seven very hot, Jupiter-like exoplanets.
The observations reveal 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.
“This breakthrough opens a completely new window on exoplanet research...
