As they shape the Earth, volcanoes inspire and terrify humans.
New research on the Nullarbor Plain reveals the ancient climate change that separated Australia’s east and west ecosystems, shaping today’s biodiversity.
What fossil records tell us about when the Earth was first covered by plants.
The Earth isn’t permanent, but it was here for four billion years before humans arrived and should be here for several billion more.
The 2.29 billion-year-old crater in Western Australia offers clues about what massive space rock impacts meant for the early Earth.
Canadian Jeremy Hansen will be one of the next astronauts on the Artemis II mission. This announcement signals a new era in Canada’s role in space exploration.
A ‘second gold rush’ has seen amateur and professional miners return to Victoria with modern technology.
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.
Zircons formed in the hellish Chernobyl meltdown are changing how geologists understand their favourite crystals.
Diamonds form alongside a distinct purple companion. We studied it to reach a conclusion about how rare they might actually be.
To us, Earth’s landscapes might change very little. But over millions of years, our planet’s surface has shifted in innumerable ways.
Earth doesn’t just have an inner core. It also has an innermost inner core, a solid ball within the solid ball in the very middle of the planet.
Fossils aren’t just pieces of the past that allow scientists to look backwards. They can play a role in modern policy decision-making, too.
We may never know exactly when the next big quake will hit – but we can have a pretty good idea of the odds.
Meteor impacts are an inevitable part of being a rocky planet in space. The craters they leave behind are a window into the tumultuous history of Earth.
A puzzle over the identity of an extinct bird that laid eggs across Australia has been solved.
Starting at the surface, you would have to dig nearly 2,000 miles before reaching the Earth’s core. No one could survive that trip – and the 10,000-degree F heat once there would vaporize you anyway.
It’s been 200 years since the discovery of one of the oldest human burial sites in western Europe on the Gower peninsula in south Wales.
Earthquakes originating underneath the ocean are often accompanied by tsunami warnings. Here’s what determines the tsunami risk.
