Accurate estimation of propellers rotation rate is crucial for effective radar classification of drones and provides quite valuable information on its potentialities. This paper investigates several ...

The planet’s rotation fluctuates as it travels around the sun, and measurements suggest we’re losing more than a millisecond ...

Earth is expected to experience slightly shorter days in the coming weeks as the planet spins faster due to the changing position of the moon, according to a report by Live Science.

July 9 was predicted to have a shorter "length of day" than usual due to an increase in Earth's rotation speed. See which ...

On July 9, 2025, scientists at the International Earth Rotation and Reference Systems Service (IERS) reported that the Earth completed its rotation approximately 1.3 to 1.6 milliseconds faster than ...

We all know that our days are longer or shorter depending on the time of the year, but the shortest day of the year is set to happen in just a few weeks time. A scientist has warned that our shortest ...

In non-orthogonal multiple access (NOMA), user pairing, power allocation, and performance evaluation are typically performed assuming all users have equal symbol rates. However, such an assumption can ...

Figuring out the ages of stars is fundamental to understanding many areas of astronomy—yet, it remains a challenge since stellar ages can't be ascertained through observation alone. So ...

Earth is trapping much more heat than climate models forecast—and the rate has doubled in 20 years by Steven Sherwood, Benoit Meyssignac, Thorsten Mauritsen, The Conversation ...

Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before 2020, the Earth never experienced a day shorter than the ...

Here’s what you’ll learn when you read this story: Although the Earth completes one full rotation in 86,400 seconds on average, that spin fluctuates by a millisecond or two every day. Before ...

For nearly two centuries, scientists have speculated whether the Earth's rotation could be tapped as a source of electricity.
