The planets of our solar system move in ellipses. We've known this, so we are told, ever since Johannes Kepler devised his laws of planetary motion in the early 1600s. While it's true that orbits are ...

For centuries, astronomers have sought to understand the complex dance of planetary motion. The ancient belief that planets followed perfect circular orbits aligns intriguingly with modern theories of ...

Celestial mechanics has long been used as an aid for interpreting geological records. The compliment is being repaid through analysis of Mediterranean sediments. You have full access to this article ...

Retrograde mean motion resonances occur when orbiting bodies, moving in directions opposite to the dominant sense of motion, experience periodic gravitational interactions that can stabilise their ...

PITTSBURGH (KDKA) - I like to take pictures and make time lapses, and a fun thing to do is take long exposure pictures. To get a long exposure, you leave the camera's shutter open for a long period of ...

The Antikythera mechanism is one of the most astonishing discoveries in archaeology. Salvaged from a 2,000-year-old shipwreck in Greece in 1900, the intricately geared contraption was quickly ...
