NASA is planning to send a rover in 2025 to investigate "lunar swirls," mysterious light-colored patterns on the moon's surface caused by magnetism. A new study suggests that underground magma cooling could create magnetic fields responsible for these swirls, but more data is needed to confirm this theory.
The Earth's magnetic field, generated by electric currents in its liquid core, has been a fundamental force since the planet's formation. This magnetism, locked into iron-containing minerals as the Earth cooled, extends from the core to the atmosphere and beyond. The phenomenon has been known for thousands of years, with historical references to magnetic rocks like magnetite. Theoretical physicist Frank Close explores these concepts in his book "CHARGE: Why Does Gravity Rule?"
An international team of astronomers, as part of the FIREPLACE project, has produced a celestial image revealing previously unseen details of the central Milky Way, including magnetic field lines and jets of hot ionized gas.
