An Australian zircon crystal is the new oldest earth on Earth.
Not news: Mars rover discovers rock. News: rock that spontaneously appeared out of nowhere.
If only all volcanoes looked like this.
If you've ever wanted to know what it feels like to live on the surface of Mars, this job's for you.
The more we learn about Mars, the less we know, and the weirder it gets.
Rocks that somehow race around the Southern California desert have been making fools out of scientists for decades, but the mystery may now be solved.
A hunk of stone 100 million years old could be a piece of the real geological lost continent.
A team of geologists have studied earthquakes to find out how they produce gold deposits.
When it comes to creating a picture of the Earth's magnetic history, scientists have pretty good data on the strength and direction of magnetic fields in the Northern Hemisphere, thanks to the study of ancient pottery. But, for researchers looking to make a truly complete model, the problem has been the gaps in information in the southwest Pacific.
Geologists will try and tell you that it's easier to explore the moon and Mars than it is to explore the Earth's mantle. As a geologist myself, I think they're full of it, but they do have a point that we don't know a whole heck of a lot about what's going on beneath our feet. To find out, an international team wants to drill into Earth's mantle, 3.7 miles below the ocean.
