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

This summer has seen the shortest days in Earth’s recorded history Scientists break down the reasons why days are getting shorter—and the mystery they're still trying to solve about Earth's core.

Earth is spinning faster than usual, with July 22 set to be one of the shortest days ever, just 1.34 milliseconds shy of a full 24 hours.

Why is Earth spinning faster now? Twenty-four hours (86,400 seconds), or a full day, is the time it takes for the Earth to rotate fully on its axis.

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.

Tuesday, July 22 will be the second-shortest day of the year, as Earth completes a full rotation in less time than usual. The planet on Tuesday will experience a shorter rotation than the typical ...

Is Earth’s rotation speeding up? Why today, July 22, may be another of 2025's shortest days Experts say Tuesday, July 22, could end up being the shortest day of all of 2025.

July 22 will be the second-shortest day of the year, as Earth completes a full rotation in less time than usual.

Scientists predicted that Tuesday will be a fraction of a second shorter than normal as the Earth's rotation is moving faster.

Earth may be safe from an impact by the asteroid 2024 YR4, but it still has a chance of striking the moon. This lunar impact could pose a risk to space tech and astronauts.

It's a phenomenon that has left scientists baffled, but the Earth's rotation is spinning unusually fast and Wednesday may be the shortest day ever on record. The shortest day of the year could ...
