Earth naturally cycles between ice ages and warm periods based on three astronomical cycles: precession (Earth’s wobble), ...

Obliquity (40,000-year cycle): The tilt of Earth’s axis changes between 22.1° and 24.5°, affecting how much sunlight reaches ...

Most of the earth’s wobbling is a grand motion that makes its axis describe a 23° cone once every 26,000 years. This precession is caused by the pull of the sun and the moon acting on the ...

The main climatic effect of precession is to shift the season when the Earth has its closest pass to the Sun (perihelion) — the so-called precession of the equinoxes. Today, perihelion occurs in ...

The origin of life on Earth stands as one of the great mysteries of science. Various answers have been proposed, all of which remain unverified. To find out if we are alone in the galaxy, we will need ...

Changes in Earth's orbit have helped pace climatic change ... by variations in the cumulative effect of eccentricity and precession (eccentricity modulated precession), whereas higher latitudes ...

The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing ...
