For many kids, the combination of good weather and lack of school obligations makes summertime synonymous with good times. Three solid months of freedom, soaked in the Sun, without adults looking over ...

Here's how it works: The Earth revolves in orbit around the sun over the course of a year. Earth's axis is tilted 23.4 degrees from the plain of its orbit. It's called the axial tilt or obliquity. As ...

In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane; equivalently, it is the ...

Uranus, the seventh planet from the Sun, is an enigmatic world that has perplexed astronomers with its extreme axial tilt of about 98 degrees. Recent studies suggest Uranus might be tilting even more, ...

New simulations show Mars plays a key role in shaping Earth’s long-term climate by influencing its orbit and axial tilt over hundreds of thousands to millions of years.

According to our best understanding of Earth’s climate, the global average temperature has increased significantly over the past ~140 years: the amount of time for which a reliable, direct temperature ...

An illustration of the analemma—a figure-eight pattern formed by plotting the sun’s position at the same time each day over a year. We’re all familiar with the sun’s daily motion in the sky. It rises ...

There are plenty of interesting things about Uranus. Its season lasts as long as its day, it’s the second least-dense planet, and it has a collection of 27 moons. But maybe the most puzzling fact ...
