Story summary

A study by the University of Rochester finds Earth's magnetic field carries atmospheric ions to the Moon via solar winds along field lines during full Moon.
The transfer has occurred for billions of years, challenging theories that it happened only before Earth's magnetic field formed.
Lunar regolith may contain water and nitrogen, resources that could support future human activity.
The findings could inform atmospheric evolution on Mars.
