Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in ...

On top of all this, everything in the solar system is held in place by the Sun's gravity, and so on. Gravity diminishes over ...

Astronomers believe they've discovered a spiral structure inside the Oort cloud that surrounds our solar system.

Groundbreaking research reveals the Oort Cloud's shape as a spiral structure, challenging traditional beliefs about its random collection. NASA's Plei ...

That's because the planet is about to get very, very hot. You see, the sun's tremendous gravity pulls the Earth right toward it. Meanwhile, the planet is trying to whiz away in this direction.

As the planets formed, their gravity scattered countless icy bodies to the outermost reaches, where they continue to orbit the Sun to this day. Until now, scientists knew the Oort Cloud existed ...

Parker’s is now a seminal paper on solar wind. Why doesn’t gravity stop the sun’s matter escaping? How does the matter come out of the sun? If you think about the analogy with the Earth’s ...

Gravity also acts between the Moon and the Earth and keeps the Earth in orbit around the Sun. The force that pulls things to the centre of Earth (and other planets) is called gravity. Gravity also ...
