If you feel like you never have enough hours in the day to do everything you want to do, don't worry. You just have to wait ...

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 ...

Every second, the Earth spins at an incredible speed, completing a full rotation in just 24 hours. While this may seem ...

The rotation of Earth's inner core began to slow down more than a decade ago, altering the length of our days by fractions of a second. Researchers from the University of Southern California (USC) ...

Earth’s rotation is slowly slowing, scientists say, meaning days are getting longer, though the change takes millions of ...

The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet. The results of the research, ...

Earth’s Rotation Day 2026, observed on January 8, highlights how Earth’s constant rotation shapes day and night, climate, ...

Our 24-hour day measures Earth’s rotation relative to the Sun, known as a solar day. This is slightly longer than Earth’s ...

While the Earth on June 29 did indeed record its shortest day since the adoption of the atomic clock standard in 1970 — at 1.59 milliseconds less than 24 hours — scientists say this is a normal ...

In the 1850s British railway companies started introducing a single standard time to make their timetables consistent. Before that, every city would set its own clock based on the observation of the ...

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.
