New research suggests that Venus’ crust is broken into large blocks – the dark reddish–purple areas – that are surrounded by belts of tectonic structures shown in lighter yellow–red. Paul K. Byrne/NASA/USGS

The surface of Venus is cracked and moves like ice floating on the ocean – likely due to tectonic activity

Researchers used decades-old radar data and found that some low-lying areas of Venus’ crust are moving and jostling. This evidence is some of the strongest yet of tectonic activity on Venus.

The eruption of Mount Nyiragongo: its health effects will be felt for a long time

Nyiragongo is one of the most dangerous volcanoes in the world because of its fast-moving lava. It can flow at a speed of about 100km per hour.

Mount Nyiragongo’s volcano: why it’s unique and treacherous

National governments need to wake up to the volcanic risks posed by tectonic rifting around Mount Nyiragongo.

Huge volcanic eruption didn’t cause climate change and mass extinction 140 million years ago

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.

Meteorites from Mars contain clues about the red planet’s geology

Martian meteorites allow scientists here on Earth to decode that planet’s geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.
