Here's how the astronomical phenomenon influences our planet—from the length of our seasons to the way Earth moves through ...

Planet Earth is spinning a little faster today — resulting in one of the shortest days of the year. But the change will be so minuscule you won’t even notice. We’re talking even less time than the ...

Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars. Scientists call this difference crucial to ...

The planet’s rotation fluctuates as it travels around the sun, and measurements suggest we’re losing more than a millisecond during the long days of summer. By Jacey Fortin This article was updated ...

The Earth is predicted to increase its rotation speed in July and August, once again bucking the trend of a slower rotation over time. Though there are clear reasons for the increased rotational speed ...

Though we sum up a day as 24 hours and a year as 365 days, Earth's rotational and orbital speeds aren't exactly consistent. Instead, both fluctuate, swayed by atmospheric drag, tidal forces, changes ...

The Cambrian Explosion in which life on Earth underwent massive diversification was likely triggered by eccentricities in Earth’s orbit around our Sun. Or so say the authors of a new paper just ...

A strange shift in Earth's rotation is making our days milliseconds shorter — and scientists are racing to understand why. When you purchase through links on our site, we may earn an affiliate ...
