Moon gravity shows weird pattern

Cape Town - The US space agency Nasa has uncovered anomalous gravity lines on the Moon.
The Moon was part of the Grail (Gravity Recovery and Interior Laboratory) mission which is designed to help scientists understand the structure and composition of Earth's only natural satellite.
The two orbiting spacecraft found that the gravity on the Moon was uneven and identified mysterious lines of intense gravity, known as mascons - for mass concentrations.
Jay Melosh, a Grail co-investigator at Purdue University said the mascons were the result of early impacts of asteroids with the Moon which cooled more significantly than the Earth.
The study found that the mascons on the Moon are concentrated at the centre from the mostly iron ore in large asteroids that collided and may provide clues to the formation of the Earth 4.5 billion years ago.
