Deep in China’s Hubei province, a structure designed to tame nature may also be nudging the planet’s rotation. The Three ...

We still don’t fully understand what determines the rotation rate of giant planets; this is a key open topic in planetary science. Let’s take a look at the differences between the giant ...

THE recent radar measurements of Mercury indicate that the period of rotation of the planet is 59 ± 5 days 1. This result is in complete disagreement with the previously quoted value of 88 days ...

However, there is a slightly more complicated theory: the planet's fast-moving atmosphere interacting with its surface altered its speed and rotation. "We think of the atmosphere as a thin ...

If precise enough, the measurements of the rotation with all of the wobbles place constraints on the structure and composition of the very deep parts of the planet, Dr. Le Maistre said.

Between May 20 and 24, the moon, Saturn and Venus will meet in a mini 'planetary parade,' becoming visible in the northern ...

UTC relies on atomic clocks but still keeps pace with the planet’s rotation. But as the rotation speed is not constant, the two timescales slowly diverge. This means a “leap second” must be ...

Why Trust Us? In recent years, the Earth’s rotation has been speeding up due to dynamics in the planet’s liquid outer core. This increase presented the possibility that scientists might soon ...

Climate change is causing widespread global impacts, but now scientists are finding that it's altering the very planet itself. Earth's rotation is slowing down, extending the length of a day ever ...
