In the Northern Hemisphere, Earth’s axis of rotation, referred to as the “North Celestial Pole,” currently points to a spot on the celestial sphere near the star Polaris (the “North Star” or “pole ...

New geological evidence suggests that the slow wobble of Earth’s axis may have triggered rapid climate swings during the Late Cretaceous greenhouse world.

Regular readers of my column certainly know how to use the Big Dipper to find the North Star (aka Polaris). Some folks believe Polaris is important because it’s the brightest star in the heavens, and ...

A new study from China University explores how millennial-scale climate variability, traditionally linked to ice-sheet dynamics, occurred during warm greenhouse house periods when ice sheets were ...

A pattern of encroaching and retreating ice sheets during and between ice ages has been shown to match certain orbital parameters of Earth around the sun, leading to researchers being able to predict ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Earth’s elliptical path around the Sun does more than keep the planet in a stable orbit. Because that path is not a perfect ...
