Researchers find that shifts in Earth’s orbit can trigger abrupt climate changes, even in warm periods without ice sheets.

Earth’s slow axial wobbles—known as precession cycles—do not just shape long-term climate trends. A new study led by ...

This is the first time that disk-jet co-precession has been clearly observed in a black hole system, which is truly exciting, ...

The ebb and flow of Pleistocene glacial cycles is not random; it follows a predictable pattern dictated by the distinct and deterministic influence of Earth’s orbital geometry, according to a new ...

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 ...
