The moon appears to be far richer in water than previously believed, following the discovery of 'melt inclusions' in rocks brought back from the Apollo mission in 1972.
There's a vast ocean of molten magma beneath the surface of Jupiter's moon Io, NASA scientists have found.
Geologists have been testing a technique to generate energy from magma, after molten rock unexpectedly flowed into an exploratory well they'd been drilling in Iceland.
Scientists at the Woods Hole Oceanographic Institution (WHOI) have observed the Earth's crust forming in an entirely unexpected way — and one that could affect the world’s climate.
