Determining Earth's bulk composition is difficult because so little of the planet is directly accessible. As a result, most estimates derive from a comparison of Earth rocks with the planet's probable ...

Our planet has an outer layer made up of several plates, which move relative to one another. While we may take this knowledge for granted, this theory of plate tectonics was only formulated in the ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

Working with colleagues from NASA, a Florida State University researcher has published a paper that calls into question three decades of conventional wisdom regarding some of the physical processes ...

It's the first time Earth's geologic record — information found inside rocks — has been used to create an animation of this kind. When you purchase through links on our site, we may earn an affiliate ...

Earth has a large amount of water and a relatively large moon, which stabilizes Earth's axis. Both are essential for life to develop on our planet. Scientists have now been able to show that water ...

The moon orbits Earth — right? The answer is actually a little more complicated than that. The moon is circling a point about 3,000 miles from our planet's center, just below its surface. Earth is ...

Ever wonder what's in the miles and miles of rocky crust just below your feet? James O'Donoghue, a planetary scientist at the Japanese space agency (JAXA), asked himself that in 2019. So he sent a ...

Mexico's western coast is again dealing with rain, wind and rough surf from another tropical storm. NOAA's GOES-West satellite saw the formation of Tropical Storm Simon on Oct. 2. A NASA animation of ...

Researchers investigate the effects of oxygen content on the melting of mantle rocks and the formation of early Earth magma It is widely accepted that the early Earth largely consisted of molten magma ...
