Atomic clocks — among the most precise instruments humans have ever built — have been keeping track of Earth’s spin since the ...

While it’s unlikely anyone would notice a missing millisecond, there’s potential this speed-up could have ramifications for ...

Earth's spin, of course, is not the only motion we have in space. Our orbital speed around the sun is about 67,000 mph (107,000 km/h), according to Cornell . We can calculate that with basic geometry.

Earth is expected to spin slightly faster on three specific days in July and August: July 9, July 22 and August 5. This could ...

But what if the Earth did stop spinning. To put it mildly, it would be terrible and mean almost certain death for all humans and almost all animals. If you are at the equator, you ...

Earth is set to experience unusually short days in July and August 2025. The Moon's orbital position is subtly accelerating ...

A solar day should last exactly 86,400 seconds, or 24 hours. The scientific community is concerned about how the Earth's rotation is accelerating. In this regard, astrophysicist Gr ...
