The Hubble Space Telescope saw Comet 41P stop spinning completely, and then restart, but in the opposite direction.

A new study suggests climate change is doing something few people could ever notice: it’s making Earth’s days slightly longer.

This week's question comes from Morning Brief reader Robert, who asks, "Do tornadoes rotate clockwise or counterclockwise?

A solar eclipse recorded in ancient China more than 2,700 years ago is helping scientists refine measurements of Earth’s rotation and investigate the Sun’s past behavior.

The discovery of a newborn magnetar inside a distant supernova helps explain why some stellar explosions shine far brighter ...

New geological evidence suggests that the slow wobble of Earth’s axis may have triggered rapid climate swings during the Late Cretaceous greenhouse world.

Earth’s gravity has a lot to do with what people think is up and what is down. Things fall down toward the ground, but that ...

The new study described this "almost unprecedented rate of increase" in the length of an average day as a quantifiable ...

Rising sea levels are slowing Earth’s rotation, lengthening how long an average day lasts. And the current rate of increase to a single average day—1.33 additional milliseconds per century—is ...

In this spirit of rigorous worldbuilding, we just published a new study where we merged the disparate disciplines of literary worldbuilding and climate modelling. We used complex computer programs – ...

New factors could be impacting the rate at which the Earth is spinning, scientists have said. It turns out that the days getting longer isn't just because Spring is finally on the way. Scientists ...

But new research suggests a new player is making an impact: us. By studying foraminifera, tiny single-celled marine organisms that leave behind fossil shells, a team of researchers from the University ...
