Finally, the Earth moves a little bit beyond one complete revolution, so the stick again points towards the sun for a second local noon. The sidereal day is just a little bit shorter—approximately 23 ...

“Getting that to cross the equator, where the Coriolis force is essentially zero, is kind of impossible because it means you ...

At any given time, about two-thirds of Earth's surface is covered by clouds. Overall, they make the planet much cooler than ...

Equator plans to invest the fund in 15 to 18 startups, writing $750,000 to $1 million checks for companies at the seed stage and $2 million for those at Series A. Techcrunch event Save $200+ on ...

As well as the equator having lower gravity, Earth's spin is faster there, giving rockets an extra boost when launched from the line. Today, the equator passes through 13 countries.

At precisely 5:01 a.m. ET on Thursday, the sun's rays fall directly on the equator, marking the first official day of spring. Meteorologists consider March 1 the start of spring. An equinox occurs ...

So much ice is melting at the Earth's poles that it's affecting the rotation of the planet, scientists say. Its spin is slowing down slightly, causing days to get longer.

Melting ice is slowing Earth's spin and causing changes to its axis, new studies find. The shifts are causing feedback beneath the surface, impacting the planet's molten core.

It isn’t unheard of for planets to capture asteroids, says Tomkins, and it is thought that Earth pulls a kilometre-scale object into temporary orbit around once every 10 million years.

The ionosphere stretches from 50 to 400 miles above the planet and marks the boundary between our planet's atmosphere and outer space. While it houses most satellites orbiting the Earth, it's ...

In that scenario, climate change would overtake the primary force that has been slowing Earth down for billions of years: the moon’s pull on the planet’s tides.

New NASA-led research reveals that global warming is altering wind patterns and shrinking Earth's reflective cloud zones.
