Scientists were not previously certain how the precious stones arrived at the Earth’s surface.

As continents grind across ‘hotspots’ in Earth’s mantle, we can get volcanoes erupting on the surface. Studying these can reveal much about our planet’s evolution.
Jupiter’s moon Io has more than 400 active volcanoes on its surface.
Decades old images reveal that a volcano erupted on Venus in 1991.
A scientist who led one of the first projects to map the Hawaiian Islands’ deep volcanic plumbing explains what’s going on under the surface as Mauna Loa erupts.
Ancient blobs deep inside the Earth gather together and break apart like continents, according to new research.
Pluto has recently active icy volcanoes, that have erupted water ice.
Huge volcanic eruptions were once believed to be the cause of mass extinctions on Earth. However, new research has found that super eruptions did not necessarily result in mass extinctions.
The end-Triassic mass extinction was a cataclysm for the world’s prehistoric species, killed off by volcanoes that altered Earth’s seas and skies. But new research shows it didn’t happen when we thought.
More and more evidence has accumulated which shows that changes in global and regional climate over the last 50 years are almost entirely due to human influence.
New analysis of data from the Apollo era shows that moonquakes occur close to visible faults, which may matter when setting up a moon base.
Lord Howe Island is part of an underwater volcanic chain much older than first thought, with the possibility of new islands still to form.
They erupted for billions of years and make Earth’s volcanoes look like molehills. Here’s what we know and what we don’t know about them.
The planet is more similar to Earth than any other – except when it comes to supporting life.
