Nelson Mandela Day 2025: As the world marks Nelson Mandela International Day 2025, we pause to ask: why does his legacy still matter today?In a time of global conflict, rising authoritarianism ...

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.

Earth just had one of its shortest days on record, and it's not alone. Our planet is spinning faster, with two more shorter-than-usual days ahead.

The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

Since then, Earth has broken that record every year by roughly half a millisecond. The shortest day on record was July 5, 2024, when Earth completed its rotation 1.66 milliseconds faster than normal.

Scientists anticipate that Earth's rotation will quicken enough to create three shorter days between July and August, starting Wednesday, July 9.

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 ...
