Story summary

Researchers say Earth-origin charged particles contribute to haematite formation on the Moon.
Ziliang Jin of Macau University notes the Earth–Moon connection.
The phenomenon, called "Earth wind," occurs when Earth blocks solar particles and its atmospheric particles reach the Moon.
Lab experiments show high-energy oxygen ions can transform iron-rich lunar minerals into haematite, while hydrogen ions revert haematite to iron.
