"With an orbital period of 570 days, it is a relatively cold gas giant planet," said Guðmundur Stefánsson of the University ...

Ever since Isaac Newton famously talked about gravity, its dominance as a force in our solar system has been well known. It's responsible for the orbits of the planets and their satellites, but there ...

Could humans survive on other planets? What would it take to live on Mars, Venus, or even a moon like Titan? From low gravity to toxic atmospheres, every planet presents a unique challenge. Watch as ...

The number of planets that orbit the sun depends on what you mean by “planet,” and that’s not so easy to define ...

To get somewhere in outer space, you can’t exactly drive in a straight line. Orbits are tricky things, and sending a probe to ...

Cosmic forensic experts are reconstructing the magnetic field around an infant star from the planet-forming disk of gas and dust around it.

Astronomers may have found a star racing through our galaxy at an incredible speed—dragging a planet along with it! If ...

Currently, I am determining the atmospheric composition and dynamics of two super-puffs (Kepler 51b and Kepler 51d) in order to better understand how these low gravity planets maintain their ...

We commonly experience gravity by being pulled downwards by the Earth. Gravity keeps all of the planets (including Earth) in orbit around the Sun. It also keeps the Moon in orbit around the Earth.
