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 ...

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.

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

If you haven’t accomplished as much this summer as you had hoped to, you can blame forces far beyond your control: a few of these dog days, by one measure, are among the shortest you’ve ever lived ...

What if the Earth just... stopped spinning? This video dives into a terrifying thought experiment: what would happen to our planet, our weather, and human life if the Earth's rotation came to a halt, ...

It wouldn’t be summer without the stretched out days. The dawns break early and the dusks come late, affording more time for lazy beach trips and long barbecues under the slow curve of the sun. But ...

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.

Precise orbit determination (POD) is vital for satellite navigation, positioning, and timing services, especially as large Low Earth Orbit (LEO) constellations grow in scale. A new method integrates ...
