About 65 million years ago, a huge asteroid slammed into the Earth and wiped out three quarters of all life on Earth, including the dinosaurs. Now, Yale researchers have found evidence that oceans became too acidic for marine animals to take.

South African researchers found new evidence supporting the hypothesis that Earth was struck by an asteroid 12,800 years ago, causing global cooling.

Scientists have found some of the earliest direct evidence of life, in the form of organic remains in 3.5-billion-year-old stromatolites in Australia.

A drilling expedition to the Chicxulub crater turned up new details of the immediate aftermath of the asteroid impact that killed the dinosaurs.

The magnetic north and true north will synch at Greenwich, England over the next two weeks for the first time in 360 years.

A huge raft of volcanic rock is floating towards Australia – and scientists say it'll help the ailing Great Barrier Reef.

Compasses point north – that’s a pretty constant fact of life. But it hasn’t always been the case, as the north and south poles flip on a semi-regularly basis. Exactly how long this process takes has been up for debate, and now a new study suggests it happens far more slowly than previously thought.

A new study has used simulations to show that even Earth-like planets completely encased in ice could still have areas warm enough for life, muddying up the already-murky definition of habitable worlds.

Many of us will know what bubbling lakes of lava within volcanoes look like. After all, we've seen them our entire lives in movies and on TV. But that doesn't mean they're common. In fact, only seven lava lakes have been found so far, until now.

It’s hard to get a clear idea of the wild early days of Earth. But a new study by researchers from the University of Adelaide raises the possibility that continents may have risen out of the sea much earlier than is currently believed, before being destroyed once again by tectonic activity.​

A field study of the deadly 2014 landslide in Washington State is providing new insights into how such large-scale slides operate. A team from the US Geological Survey did detailed measurements and sampling of the post-disaster site, allowing them to build a detailed timescale of the event.

A team of volcanologists at the University of Missouri turned fashion models recently as they showed off prototype lava suits that are designed as comfortable, hard-wearing field outfits for scientists bound for the slopes of Vesuvius and the like.
