You should go beyond diamonds to find some of the rarest minerals in the world. Scientists have inventoried and categorized all of Earth's rare mineral species described to date.
Scientists have made an astonishing finding. They've discovered mantle rocks with signs of life in addition to evidence of unique carbon cycling and ocean crust movement.
It turns out that there may be evidence for more recent clay formation on Mars, which may tell researchers a bit more about the Red Planet and show a bit more about the conditions that may have once been hospitable to Martian life.
Scientists have learned a bit more about moon rocks and why they're more depleted in volatile elements than those found on Earth.
Scientists have captured the highest-resolution radar images yet of an asteroid that flew by Earth on Halloween. The new images reveal a bit more information about the surface features of the asteroid.
Scientists may have solved the mystery of organic matter found in lunar samples from the Apollo missions. The findings may tell researchers a bit more about the moon and about future samples that are taken.
After news of extraterrestrials, the public is primed for more sightings. In this case, though, it's a Buddha statue on Mars-sort of.
Where did pebbles on Mars come from? They may have just been pushed by a river that existed millions of years ago. Scientists have examined mages of a few rocks and found that their smooth shape may be due to plentiful past water.
Scientists have used new data to find out that Earth's inner core was formed about 1 to 1.5 billion years ago as it "froze" from the surrounding molten iron outer core.
Could Io have an underground magma ocean? Tides flowing in a subsurface ocean of molten rock could explain why Jupiter's moon appears to have its volcanoes in the "wrong" place, according to a new study.
Over the course of billions of years, continents break up, drift apart, and are pushed back together again, but the cores of continents, called cratons, are stable--at least that's what scientists thought.
