Why we need to get back to Venus

This hot, acidic neighbor with its surface veiled in thick clouds hasn't benefited from the attention showered on Mars and the Moon. But Venus may offer insights into the fate of the Earth.

Earth’s core has been leaking for billions of years

New findings suggest the core has been leaking for the past 2.5 billion years, and that could help scientists understand how the core was formed.

We made a moving tectonic map of the Game of Thrones landscape

Even in this fantasy world, geological processes like tectonic plate movement, earthquakes and volcanic eruptions would have built the mountains, carved the rivers, and created vast oceans.

How the Pilbara was formed more than 3 billion years ago

The remote Pilbara region of Western Australian formed many billions of years ago when the Earth was much hotter and the crust softer than it is today.

Aftershocks hit Papua New Guinea as it recovers from a remote major earthquake

Fresh earthquakes and aftershocks hit parts of Papua New Guinea following February's deadly quake. It's Australia's slow push north that's part of PNG's seismic activity.

A map that fills a 500-million year gap in Earth’s history

You would not recognise Earth if you saw it 500 million years ago - the lands, oceans, climate and life were all very different. Scientists now have a new map of the deep history of Earth.

Making waves: the tsunami risk in Australia

Australia is surrounded by ocean, so is not immune to the effects of tsunamis. But how significant is the risk?
