Icelandic magma marks geothermal heat milestone

Geothermal power development has traditionally been about drilling down into subsurface reservoirs of hot water. Enhanced geothermal is expanding the field to include dry, permeable hot rock where water can be added.

Mercury once had vast lava ocean

Mercury may once have had a large ocean of magma, Messenger data shows, shortly after its formation about 4.5 billion years ago.

'Trigger' found for explosive eruptions

Scientists say they've identified the trigger for the largest explosive volcanic eruptions on Earth.

Unique 'magma sombrero' found in Andes

Scientists examining 20 years of satellite data have found a sombrero-shaped bubble of magma 62 miles across - and, appropriately, located in South America.

Huge magma reservoir growing under Santorini

A giant 'balloon' of magma has been welling up under the Greek island of Santorini, raising it an extra five and a half inches above the sea.

Small exoplanet may be covered in magma

Astronomers using NASA's Spitzer Space Telescope have discovered what may be the nearest world to our solar system that's smaller than Earth.

Super-eruptions can develop super-fast

Supervolcanoes may be able to form in just a few hundred years - far, far more quickly than previously believed.

Volcanic activity detected on Greek island

The volcanic Greek island of Santorini - named by the BBC as the world's best island last year - appears to be working up to an eruption, its first for over 60 years.

Why are there no volcanoes on the moon?

Scientists believe they've discovered why the moon has no active volcanoes, despite containing plenty of liquid magma.

Moon has much more water than thought

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.

Magma ocean lies beneath Io's surface

There's a vast ocean of molten magma beneath the surface of Jupiter's moon Io, NASA scientists have found.

Geologists tap magma as high-grade energy source

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.

Strange magma eruptions could affect world's climate

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.
