Earth's axial precession is a gyroscopic wobble, analogous to a spinning top, causing its axis of rotation to trace a cone over time. The primary cause of Earth's precession is the gravitational ...

Aren’t the summer days supposed to be longer and the winter days shorter? Since when have things gone in reverse for the summertime? Since now, maybe? Starting today? Okay, here’s what’s going on.

China’s massive Three Gorges Dam has reportedly caused a subtle but measurable shift in the Earth’s axis and a slight increase in the length of a day, an effect confirmed by scientists at NASA’s ...

If you've felt like summer days are flying by, you're not wrong—at least not scientifically. Experts have observed that Earth's rotation is speeding up, making some days slightly shorter than 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 ...

In a “normal” electrocardiogram (ECG), the transition of the QRS axis in the precordial leads occurs between leads V 3 and V 4 (i.e., there is a dominant S in V 3 and a dominant R in V 4).

Hubble Space Telescope images of interstellar object 3I/ATLAS show a changing jet structure, including a stable sunward jet and three rotating inner jets, raising questions about their origin ...
