Earth is spinning faster than ever, and the result is a shortening of the length of our days. Since 2020, each year has ...

Thanks to a speed-up of Earth's rotation, the length of the astronomical day and the length of the clock day aren't quite ...

June 19, 2025 — During Earth's ancient Snowball periods, when the entire planet was wrapped in ice, life may have endured in tiny meltwater ponds on the surface of equatorial glaciers.

Regardless of the model (you can choose from a 150mm and 120mm models), you benefit from a CG-4 equatorial mount, which means the polar axis is parallel to the Earth's rotation.

Well, no. The moon's orbit velocity is faster than the Earth's rotation, meaning the moon's shadow will move quickly across the Earth from west to east. (Here's an AR demonstration of how the ...
