Uncovering the role of oxygen concentration in the formation of early Earth magma ocean

It is widely accepted that the early Earth largely consisted of molten magma, forming a global ocean of magma. This extreme state of Earth was likely caused by the intense heat generated from ...

‘Slushy’ magma ocean led to formation of the Moon’s crust

Scientists have shown how the freezing of a ‘slushy’ ocean of magma may be responsible for the composition of the Moon’s crust. The scientists, from the University of Cambridge and the Ecole normale ...
