Earth will complete its daily rotation between 1.25 and 1.51 milliseconds faster than usual, and scientists aren't quite sure why.

China’s Three Gorges Dam is so massive that filling its reservoir nudges Earth’s spin by billionths of a second. It’s a tiny ...

Due to the influence the Earth plays on the moon’s momentum, the Earth’s rotation slows down in response, as explained by DiKerby. However, given that this is such a minor change in distance annually, ...

The Moon, our constant celestial companion, is drifting away from Earth at a slow but measurable rate. According to a ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...

Tides come from a difference in gravity across an object. The force of gravity exerted by the Moon is about 4% stronger on the side of Earth that faces toward the Moon, compared to the opposite side ...

Michigan residents many experience one of the shortest days of the year on Tuesday, Aug. 5, though the difference is so small, you won't even notice it. If forecasts hold, Aug. 5 could be 1.34 ...

Learn more about tides and tidal bulge, and how they’re contributing to the moon drifting away.

Long ago, the Moon was much nearer Earth. Scientists believe a protoplanet collision created the Moon 4.5 billion years ago.

The study highlights how longer days allowed cyanobacteria to photosynthesise more oxygen because their activity depends not just on sunlight but on the timing of their metabolic processes.

Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have occurred several times over the last few years, haven't had any effect on daily life, but they also ...
