Using JWST, astronomers uncovered auroras, exotic clouds, and storms on a blazing rogue planet. Brilliant aurora-like ...

Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. July 9 was the first of three days in which a millisecond or more could be shaved off the clock on ...

Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before 2020, the Earth never experienced a day shorter than the ...

Scientists announced Monday that Earth is rotating slightly faster than normal, resulting in what is expected to become the second-shortest day ever recorded since precise atomic timekeeping began.

Just as passengers don’t feel the plane’s speed while smoothly cruising, we don’t feel Earth’s movement because we’re ...

Earlier this month, the Earth spun just a bit faster than usual on July 9 and is expected to do so again on July 22 and Aug. 5, according to the website TimeAndDate. Over a millisecond was reportedly ...

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 ...

The Three Gorges Dam in China is large enough and transports enough water that it affects Earth's rotation by 0.06 ...

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 Moon appears unchanging in the night sky, but its movement hides a slow transformation. For decades, scientists have observed that our satellite is gradually moving away from Earth, year ...

Early Earth lacked life’s essentials until a collision with Theia added them. This chance event made life possible. After the Solar System formed, it took no more than three million years for the ...

The Earth’s climate is a dynamic entity, continuously evolving over billions of years with alternating periods of extreme ...
