A team of international researchers say they've uncovered new data on the world's first recorded solar eclipse using a ...

The Mechanics of Earth's Spin 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 ...

Ancient Chinese astronomers observed a solar eclipse in 709 BCE with remarkable detail. These old records are now helping ...

The Earth's rotation is about to accelerate significantly. According to scientists, July 9, July 22, and August 5 of this year will be some of the shortest days in recent memory as a result, slicing ...

Because this record survived, we know more about ancient Chinese history, the rotation of the Earth, and past solar activity ...

NPR's Ayesha Rascoe talks to John Vidale, professor of earth sciences at the University of Southern California, about new research suggesting the rotation of Earth's inner core may be slowing down.

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

Warming across the Arctic is not only melting ice but it’s also causing another issue: Changing the speed at which the earth rotates, according to Duncan Agnew, a geophysicist with the Scripps ...

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 ...

We’ve probably all had a few conversations with people who hold eccentric scientific ideas, and most of the time they yield ...

The rotation of Earth's inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores. The solid inner ...

Humanity's increased release of greenhouse gasses has raised the planet's temperature, and no one expects that to stop any time soon. As the globe warms, a study shows it is also spinning more slowly.
