Moon rocks show magnetism hints at ancient lunar core
Space Center reports lunar samples exhibit permanent magnetism suggesting a once molten iron core. Dr. S K Runcorn notes a planetary magnetic field could have existed early in the Moon's history, now weakened as the core cooled. Mars imagery also shows new pits and fissures, with rilles likely formed by thawing ground ice or wind-blown dust, indicating ongoing planetary evolution.
