Megastructures have big impacts on the world - namely the people around and the environment they affect. However, this one ...

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 ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...

Would you guess that the Earth is spinning at 1,000 mph around its axis and at the same time hurtling through space on its ...

Scientists are also investigating changes in the rotation of the Earth's inner core. They suspect that couplings with the Earth's mantle could contribute to ...

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 ...

If you haven’t accomplished as much this summer as you had hoped to, you can blame forces far beyond your control: a few of these dog days, by one measure, are among the shortest you’ve ever lived ...

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 ...

August 5th, 2025, is predicted to be one of the shortest days of the year, approximately 1.34 milliseconds shorter than 24 hours. Scientists attribute this phenomenon to changes in the Earth's core ...

A 250-day experiment using a ring laser achieved unprecedented accuracy in measuring Earth's axial wobble (nutation and precession), surpassing previous gyroscope and ring laser technologies by a ...
