United KingdomScientists using data from NASA's MAVEN mission have discovered that auroras on Mars form through a process similar to Earth's auroras, driven by a miniature version of the Dungey cycle. Published in Nature Communications, the study reveals that Mars' crustal magnetic fields—formed billions of years ago—create localized auroras by facilitating magnetic reconnection, akin to Earth's global magnetic field. Unlike Earth, Mars lacks a global magnetic field, relying instead on isolated, magnetized regions in its crust. The findings provide insight into how charged particles interact with Mars' atmosphere and contribute to atmospheric loss. The MAVEN mission ended in 2025 after losing contact with ground stations, but its data continues to inform planetary science.
