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.

State weather bureau PAGASA said Thursday that the day and night will share nearly the same length around the world on ...

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 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 ...

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 ...

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

precession, and obliquity, which have to do with the shape of the Earth’s rotation, the angle of the Earth’s axis, the angle that the Earth rotates around the sun, and how these things change ...

William Hopkins read the third part of his paper “On the phenomena of Precession and Nutation, assuming the Interior of the Earth to be a Heterogeneous Fluid”. The objects of researches of ...

This axial tilt varies between 22.1° and 24.5° on a 41,000-year cycle. Changes in obliquity influence the intensity of seasonal climate variations, with a greater tilt resulting in more pronounced ...

The private Fram2 mission is launching later today, sending a crew of amateurs to an unprecedented polar orbit—a frontier ...
