Earth will complete its daily rotation between 1.25 and 1.51 milliseconds faster than usual, and scientists aren't quite sure why.

However, a recent trend shows that Earth's rotation is speeding up, and since these faster days are mostly explained by the moon's orbit, science has yet to fully explain why. A research paper ...

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

To find out how fast the Earth is spinning at all, you need to find a reference frame in which, ideally, nothing is moving.

University of Reading’s Dr James O’Donoghue explains why no day is ever really the same – horologically speaking.

The moon’s orbit is not only elliptical, however, but cockeyed too, angled anywhere from 18° to 28° relative to the Earth’s equator.

Modern satellite constellations such as OneWeb, Starlink and CENTISPACE promise global communications and navigation capabilities using low-Earth orbit (LEO) ...

The autumn night sky in Ireland is an observer's treasure-trove and the first celestial event of the season arrives on September 7 with a lunar eclipse and blood moon ...

Earth is the planet we have the best opportunity to understand in detail—helping us see how other rocky planets behave, even ...
