The Lunar Magma Ocean (LMO) is the layer of molten rock that is theorized to have been present on the surface of the Moon. The LMO was likely present on the Moon from the time of the Moon's formation (about 4.5 or 4.4 billion years ago [1]) to tens or hundreds of millions of years after that time. The LMO was a thermodynamic consequence of the ...
This lunar origin hypothesis has some difficulties that have yet to be resolved. For example, the giant-impact hypothesis implies that a surface magma ocean would have formed following the impact. Yet there is no evidence that Earth ever had such a magma ocean and it is likely there exists material that has never been processed in a magma ocean ...
A vast magma ocean may once have existed on the moon's south pole, according to evidence obtained by India's Chandrayaan-3 rover. India’s lunar lander finds signs a vast magma ocean may have ...
Magma oceans are integral parts of planetary formation as they facilitate the formation of a core through metal segregation [3] and an atmosphere and hydrosphere through degassing. [4] Evidence exists to support the existence of magma oceans on both the Earth and the Moon. [1][5] Magma oceans may survive for millions to tens of millions of ...
The first lunar samples collected during the Apollo 11 mission in 1969 led researchers to the theory that the moon was once a molten ball of magma. The 842 pounds (382 kilograms) of lunar rocks ...
There was once a magma-filled ocean on the south pole of the moon, scientists recently discovered after analyzing lunar soil that revealed ancient information about the moon's origin. The study of ...
Crystallization of this magma ocean would have given rise to a differentiated body with a compositionally distinct crust and mantle and accounts for the major suites of lunar rocks. As crystallization of the lunar magma ocean proceeded, minerals such as olivine and pyroxene would have precipitated and sank to form the lunar mantle.
The impact would have released enough energy to liquefy both the ejecta and the Earth's crust, forming a magma ocean. The liquefied ejecta could have then re-accreted into the Earth–Moon system. [53] [54] The newly formed Moon would have had its own magma ocean; its depth is estimated from about 500 km (300 miles) to 1,737 km (1,079 miles). [53]
