The first magnetosphere ever of all exoplanets was discovered in HAT-P-11b in December 2021
“The discovery of HAT-P-11b’s magnetosphere is a significant step toward an improved understanding of the habitability of an exoplanet.” said Gilda Ballester, an adjunct research professor at the University of Arizona Lunar and Planetary Laboratory and one of the paper’s co-authors.
