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.

Natural cycles in Earth's rotational axis and its orbit around the sun drive climatic changes, and now researchers have ...

"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 ...

The findings highlight the roles of precession, obliquity, and eccentricity – factors influencing the tilt and movement of Earth's axis, and the shape of Earth's orbit around the Sun – in ...

The subtle changes in orbit (eccentricity), the planet’s inclination compared to the orbit (obliquity), and the change in the direction of Earth’s rotational axis (precession) were possible ...

One type of change in Earth's orbit was responsible for the ... More information: Stephen Barker, Distinct roles for precession, obliquity and eccentricity in Pleistocene 100kyr glacial cycles ...

All winter long, I have been meaning to write about the little constellation Aries the Ram, and finally, on this last weekend ...

The Earth’s axis is at right angles to the line from sun to Earth, the sun is directly over the equator and the lengths of ...

New research suggests that Earth’s orbital variations—the slow changes in its tilt, axial precession, and shape of its ...

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 ...

HH 49/50 is one of these impact sites. It was nicknamed the "Cosmic Tornado" due to its dramatic, swirling shape. Spitzer's ...
