"Depending on where you are on Earth, you'll find more influence from precession or obliquity," he said. —Earth’s days once got 2 hours longer — and that may have triggered one of the ...

Obliquity (40,000-year cycle): The tilt of Earth’s axis changes between 22.1° and 24.5°, affecting how much sunlight reaches different latitudes. ・Precession (21,000-year cycle): Earth ...

Earth's history is a roller-coaster of climate fluctuations, of relative warmth giving way to frozen periods of glaciation before rising up again to the more temperate climes we experience today.

A pattern of encroaching and retreating ice sheets during and between ice ages has been shown to match certain orbital parameters of Earth around the sun, leading to researchers being able to ...

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 ...

The odds of an asteroid hitting Earth in 2032 now stand at 1-in-32, or a 3.1 percent chance of collision, according to the latest data from NASA. On February 7, NASA upped the likelihood of the ...

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 ...

The key players in these cycles are Earth's obliquity, the precession of its rotational axis and the shape of Earth's orbit around the sun. Breaking space news, the latest updates on rocket ...
