A new scientific model suggests that Earth’s oxygen-rich atmosphere may last for around 1 billion more years before a dramatic transformation removes the conditions that support complex life. The ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...

The Sun may carry chemical and structural traces of a large rocky planet that disappeared early in the solar system’s history ...

We like to think of our home as a nice, smooth sphere. But mapping the Earth’s gravitational field provides a different view of the planet. a new visualization of Earth looks nothing like the Blue ...

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 ...

The key to unlocking the secrets of distant planets starts right here on Earth. Researchers at Tohoku University, the University of Tokyo, and Hokkaido University have developed a model that considers ...

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 ...

Understanding Earth’s composition first requires an explanation of how planets form — a process that begins with a giant gaseous disk surrounding a star. Although Earth’s atmosphere is now just a thin ...
