Ever since its formation around 4.5 billion years ago, Earth's rotation has been gradually slowing down, and its days have gotten progressively longer as a result. While Earth's slowdown is not ...

Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. July 9 was the first of three days in which a millisecond or more could be shaved off the clock on ...

July 22 is reportedly one of the shortest days ever recorded. Before you get worried, the day will only be 1.34 milliseconds less than the standard 24 hours we’re used to, according to Space.com, so ...

Long ago, the Moon was much nearer Earth. Scientists believe a protoplanet collision created the Moon 4.5 billion years ago.

Scientists announced Monday that Earth is rotating slightly faster than normal, resulting in what is expected to become the second-shortest day ever recorded since precise atomic timekeeping began.

Earlier this month, the Earth spun just a bit faster than usual on July 9 and is expected to do so again on July 22 and Aug. 5, according to the website TimeAndDate. Over a millisecond was reportedly ...

Earth is spinning faster this summer, making the days marginally shorter and attracting the attention of scientists and timekeepers. July 10 was the shortest day of the year so far, lasting 1.36 ...

A study published in Nature Geoscience suggests that the gradual slowing of Earth’s rotation over billions of years may have played a key role in one of the most profound shifts in the planet’s ...

Observations from global observatories, including the Very Large Telescope (VLT) of the European Southern Observatory (ESO), ...

When humans pump groundwater, it has a substantial impact on the tilt of Earth’s rotation. Additionally, a study documents just how much of an influence groundwater pumping has on climate change.
