Earth’s spin is not as steady as it looks. As ice melts and groundwater is pumped from deep aquifers to the surface, the ...

Stars like the Sun support convective motions: hot plasma from the interior rises to the surface, cools, and sinks down again. This process generates pressure (or sound) waves that are trapped in the ...

Earth’s spin is not as steady as it looks from the ground. As ice sheets melt and aquifers are drained, scientists now say ...

As humans extract more and more groundwater, we are literally changing the composition of the planet, so much so that we are also shifting the tilt of the globe. According to a recent study in the ...

Humans may have altered the Earth’s rotation significantly between 1993 and 2010 alone by pumping large quantities of water out of the ground and moving it elsewhere. Alarming levels of groundwater ...

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 planets ...

Cosmic filaments are among the largest structures in the Universe, and they rotate. In a new study that stacked thousands of filaments together, they were observed to be rotating along their ...
