Earth’s Rotation Day 2026, observed on January 8, highlights how Earth’s constant rotation shapes day and night, climate, ...

Earth’s rotation is the continuous spinning of the planet around its axis, an imaginary line running from the North Pole to the South Pole. One full rotation takes about 24 hours, creating the cycle ...

The lightcurve of 2025 MN45 — the fastest-rotating asteroid with a diameter over 500 meters that scientists have ever found. The y-axis shows the asteroid’s brightness, and the x-axis shows its phase, ...

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 ...

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 ...

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 ...

Scientists have just plotted changes in Earth's axis through laboratory measurements. To do this, they constructed the world's most stable ring laser. Previously, scientists were only able to track ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. There are very few objects in the Universe that stand still; almost ...

Richard Gross, of NASA's Jet Propulsion Laboratory, calculates that last week's earthquake off Japan's coast may have shortened the length of Earth's days by about 1.26 microseconds and shifted its ...
