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 ...

Precession-driven fluid dynamics concerns the intricate motions arising when a rotating body experiences a slow, conical motion of its spin axis, a phenomenon that is pivotal in both geophysical and ...

This illustration shows how Earth’s spin axis (blue) is tilted from perpendicular, causing it to precess and trace out a circle over about 26,000 years. The brightest star nearest the North Celestial ...

Researchers from Skoltech, the University of Warsaw, and the University of Iceland have demonstrated that by optical means it is possible to excite and stir an exciton-polariton condensate, which ...

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 ...

Abrupt climate shifts are well documented in Earth's history and are commonly associated with ice-sheet dynamics during past ice ages. However, how similar millennial-scale climate variability could ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.
