Three symmetrical jets jutting out of interstellar object 3I/ATLAS are showing up in Hubble observations, puzzling astronomer ...

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 ...

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 ...

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 ...
