We still don’t fully understand what determines the rotation rate of giant planets; this is a key open topic in planetary science. Let’s take a look at the differences between the giant ...

Therefore, astronomers might expect that all of the planets in the solar system would spin in the same direction as the sun. "To look at the direction of the rotation, we always compare it to a ...

The group employed observations taken by the NASA/ESA Hubble Space Telescope to find out that the planet completes one entire rotation in 17 hours, 14 minutes, and 52 seconds. The finding appeared ...

If precise enough, the measurements of the rotation with all of the wobbles place constraints on the structure and composition of the very deep parts of the planet, Dr. Le Maistre said.

DURING the recent inferior conjunction of the planet Mercury in April, 1965, radar observations were obtained by the Arecibo Ionospheric Observatory in Puerto Rico (operated by Cornell University ...

Climate change is causing widespread global impacts, but now scientists are finding that it's altering the very planet itself. Earth's rotation is slowing down, extending the length of a day ever ...

Our planet’s rotation measured in at 1.59 milliseconds short of the normal 24-hour day on June 29, according to the International Earth Rotation and Reference Systems Service, an organization in ...

just a bit faster than the rest of the planet. Now a study published in Nature Geoscience suggests that around 2009, the core slowed its rotation to whirl in sync with the surface for a time ...
