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 ...
