Our planet may have had a recent change of heart. Earth’s inner core may have temporarily stopped rotating relative to the mantle and surface, researchers report in the January 23 Nature Geoscience.

JWST’s NIRSpec aurora maps, 10 times sharper than Cassini-era data, exposed a planetary heat engine of aurora, winds, and ...

New research gives the first accurate estimate of how much faster the Earth’s core is rotating compared to the rest of the planet. Previous research had shown that the Earth’s core rotates faster than ...

A change of milliseconds seems insignificant, but it can cause problems for our clocks, GPS and navigation apps, and satellites.

We have all been taught in school that planets revolve in the same direction as the Earth, i.e., in the counterclockwise direction. However, the universe never ceases to amaze us with its unexpected ...

For some time, astronomers have theorized that there is a connection between planetary mass and rotation. In the solar system, Jupiter and Saturn both rotate rapidly, completing a rotation in roughly ...

This image illustrates how a star illuminates and heats the day side of a synchronously rotating planet, and the phenomena of transit and occultation (eclipse). The bottom of the figure shows the ...
