💨 Abstract

Astronomers have detected the first robust evidence of magnetic fields on exoplanets using the Very Large Telescope and Gemini North. By measuring wind speeds on seven hot, Jupiter-like exoplanets, they found that hotter planets have slower winds, suggesting the presence of magnetic fields acting as a drag. These fields, comparable in strength to those in our solar system, could influence atmospheric circulation and produce intense auroras.
