We like to think of our home as a nice, smooth sphere. But mapping the Earth’s gravitational field provides a different view ...
For centuries, Earth has been pictured as a near-perfect blue sphere floating through space — but a new high-precision gravity model is revealing a far stranger reality. Using detailed measurements ...
Why should I stop talking about the Earth-moon-Sun system? There really is no reason. So, let me continue the discussion with a short tutorial that goes through the steps to make this model. There isn ...
This hands-on, guided-inquiry activity helps students to understand the geometry of lunar and solar eclipses by creating a physical, proportional model of the Earth and Moon system and observing ...
Earth supports a breathtaking range of geographies, ecosystems and environments, each of which harbors an equally impressive array of weather patterns and events. Climate is an aggregate of all these ...
A new 3-D model of the Earth will now let scientists pinpoint the sources of earthquakes and explosions around the globe more accurately than ever, researchers say. Subscribe to read this story ...
