Study Reveals Magnetic Braking on Exoplanets
Observations show slower wind speeds than predicted models for these planets.
Magnetic fields act as a braking mechanism for atmospheric charged particles.
Researchers used the Very Large Telescope and Gemini North to measure wind speeds up to 25,000 km/h.
The study provides first population-level data on exoplanet magnetic environments.
Findings help understand planetary atmospheres, water retention, and potential for life.
Earth and Jupiter have magnetic fields, while Mars lost its field billions of years ago.
