An animation by planetary scientist James O'Donoghue reveals that Earth has two types of day: sidereal days and solar days. The sidereal day happens each time Earth completes a 360-degree rotation ...

Currently, the Earth's inner core is moving slowly and in the opposite direction relative to the rotation of the Earth's surface. Scientists have noted that since the early 1970s, the inner core ...

The planet’s rotation was completed 1.59 milliseconds short of a 24-hour day on June 29, breaking the record for the world’s shortest day in modern history.

On July 19, 2020, Earth set a new milestone by completing its daily rotation 1.47 milliseconds shorter than 86,400 seconds. This wasn’t a one-off event; the trend has continued since then.

Yesterday, Reddit user Jeckee posted this short GIF of the Earth as it appears to rise over the moon's horizon: The animation, which comes from this Apollo 10 footage, was just a bit too shaky for ...

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.

For a while, the scientists reported, the core’s rotation matched Earth’s spin. Then it slowed even more, until the core was moving backward relative to the fluid layers around it.

Why does the earth's rotation not have an influence on how long is the flight from east-west/west-east? This question was originally answered on Quora by Robert Frost.

Scientists Turned the Earth’s Rotation Into 17 Microvolts of Electricity. That Could Be Revolutionary. In trying to solve Earth’s climate problem, the answer might be Earth itself.
