Today, we will explore the enormous gas giants and why they possess such astonishing rotation speeds. Going back about 4.6 ...

We’ve been arguing about this for 20 years, and I think this nails it,” said Dr. John Vidale, Dean’s Professor of Earth ...

Tracking the rotation speed of solid planets, like the Earth and Mars, is a relatively simple task: Just measure the time it takes for a surface feature to roll into view again. But giant gas ...

Today, let's talk about those massive planets in the universe. Have you ever wondered why giant planets rotate so quickly?

As for the other two planets, the team was able to constrain the spin of HR 8799 c to an upper limit of less than 14 km/s; planet b’s rotation measurement was inconclusive.

In a recent study published in The Astrophysical Journal, astronomers have introduced a groundbreaking method to map the ...

A strange shift in Earth's rotation is making our days milliseconds shorter — and scientists are racing to understand why.

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

This is how long a year is on other planets in our solar system, beginning with Mercury at about 176 Earth days to complete its orbit.
