Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...

ALTHOUGH the Earth revolves around the Sun, from our point of view we see the Sun moving around the sky along an imaginary circle called the ecliptic once every 365.256 days. This is known as the ...

Toy gyroscopes can do all kinds of interesting tricks. The most mysterious one, precession, seems to defy gravity. By definition, precession refers to a change in the orientation of the rotational ...

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 ...

Earth's axial precession is a gyroscopic wobble, analogous to a spinning top, causing its axis of rotation to trace a cone over time. The primary cause of Earth's precession is the gravitational ...
