"Moon's Hidden Giant Structure Unveiled by Scientists"

Scientists have discovered a massive structure beneath the Moon's South Pole-Aitken basin, weighing at least 2.18 billion kilograms and measuring over 300km in depth and 2,000km in length. The anomaly could be composed of metal from an asteroid or oxides from a magma ocean. The finding was made using NASA's GRAIL mission, which measures changes in the Moon's gravitational field, providing insights into its internal composition and history.
