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.
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 ...
Natural cycles in Earth's rotational axis and its orbit around the sun drive climatic changes, and now researchers have ...
One type of change in Earth's orbit was responsible for the end of ... Distinct roles for precession, obliquity and eccentricity in Pleistocene 100kyr glacial cycles, Science (2025).
then compared this data to the Earth's oval-shaped orbit around the sun, a phenomenon called orbital eccentricity. The authors found each glaciation period in the last 900,000 years followed a ...
Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of ...
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 ...
Earth's last ice age ended around 11,700 years ago and a new study predicts the next one should be 10,000 years away. But the researchers say record rates of fossil fuel burning that are increasing ...
YR4 is classified as a Near-Earth Asteroid (NEA), meaning its orbit brings it into proximity ... This orbital eccentricity means that YR4 spends a significant amount of time far from Earth ...
An international team led by researchers in Japan and Europe has discovered a new multi-planet system around a Sun-like star, ...
They mapped changes in ice sheet volumes using data from fossilized deep-sea organisms, then compared this data to the Earth's oval-shaped orbit around the sun, a phenomenon called orbital ...
The key cycles include: ・Eccentricity (100,000- and 400,000-year cycles): Earth’s orbit shifts from more circular to more elliptical, altering the intensity of seasons. ・Obliquity (40,000 ...
