Researchers trying to model what our planet will be like in 250 million years have some very bad news for us.

According to the news, our planet's core has stopped spinning and will soon reverse. What's really happening is a lot less exciting, but still pretty neat.

A new discovery of organic molecules in Martian sediment doesn't prove there was life on the red planet. But it does help build the case for it.

A world-changing super-eruption of the supervolcano under Yellowstone is now almost a cliché in disaster movies and documentaries. But there's a good chance it may never actually happen.

Determining the tallest mountains on Earth seems like a fairly straightforward task, but it actually depends on which mountains you measure and how you measure them...

Asteroids and comet brought our planet water and the chemical precursors for life. But could they have also given rise to our continents and help set plate tectonics in motion?

Tracking the magnetic north pole has been a difficult task over the last few hundred years, and even today, in the age of computers and lasers, it hasn't gotten any easier as scientists were surprised by its rapid migration towards Asia.

New models trying to infer the geology of potentially habitable moons orbiting Jupiter and Saturn hint at surprisingly cool, geologically inactive worlds, the opposite of what a diverse alien ecosystem would need.

Rocks in Tasmania and the Grand Canyon are helping geologists piece together the history of a billion year old supercontinent and a more accurate history of our planet.

Scientists are debating how humanity will be remembered millions of years from now and it won't be by our sprawling cities and historical sites. It will be by our pollution, garbage, and weapons.

Apparently middle aged planets also gain mass around their equators according to an amateur geologist very passionate about his epiphany.

No, the new study about abiogenic hydrocarbons doesn't prove that oil comes from the mantle instead of organic matter decomposing for millions of years at high pressures.

Climate change deniers seem to hold on to a long discredited Russian hypothesis that oil comes from the mantle, not from dead living things decomposing under immense pressure.

A new eye-catching proposal suggests that the Moon was spun off from Earth instead of being formed in the aftermath of a collision.

Scientists want to drill into a currently sleeping supervolcano to learn more about it. The payoff would be huge, but so are the risks.
