Resonating oscillations of a planet's atmosphere caused by gravitational tides and heating from its star could prevent a planet's rotation from steadily slowing over time, according to new research by ...

The rotation periods of Jupiter, Saturn, Uranus, and Neptune range from roughly 10 to 17 hours. Estimating giant planets’ rotation rates, however, is not easy. Because they don’t have solid surfaces, ...

The length of Earth's day is slowing down at a glacial pace of 1.8 milliseconds every 100 years. This image shows the Earth and moon as seen by NASA's Deep Space Climate Observatory satellite 1 ...

The Coriolis effect impacts global patterns and currents, and its magnitude, relative to the magnitude of inertial forces, is expressed by the Rossby number. For over 100 years, scientists have ...

Somewhere deep below Saturn s cloud tops, the planet rotates at a constant speed. Determining this interior period of rotation has proven extremely complicated. Now, with new Cassini results, a team ...

We call a day 24 hours because it’s a clean, reliable number. But Earth isn’t a perfect clock. When our planet formed 4.6 billion years ago, a day lasted a mere six hours. By the time the dinosaurs ...

Time is out of joint on Venus. The planet’s thick air, which spins much faster than the solid globe, may push against the flanks of mountains and change Venus’ rotation rate. Computer simulations show ...

Visualizing our solar system is one of those third-eye treats that never grows old. The Sun and its gravitationally bound planets, asteroids, etc. are in constant relative motion, and thinking about ...

WASHINGTON, D.C., September 28, 2018 -- The earth's rotation causes the Coriolis effect, which deflects massive air and water flows toward the right in the Northern Hemisphere and toward the left in ...
