Zero gravity, often depicted in science fiction and space documentaries, is a fascinating concept that sparks curiosity and ...

It does so differently due to how objects orbit the planet. The reason astronauts float about aboard spacecraft is because of weightlessness, not zero gravity.

An experiment involving artificial organs is just one way researchers are trying to capitalize on the weird ways low-gravity environments affect the human body.

The idea of gravity as we know it has been around for a long time. More than 300 years ago, Isaac Newton first shared his theory of gravitation, describing how massive objects are attracted to ...

Sometimes, as with the Sun and Jupiter, their mutual center of gravity or barycenter lies slightly outside one of the bodies; Jupiter is large enough that it drags the Sun in a little circle ...

Gravity also keeps the Moon in orbit around the Earth. The Moon's gravitational pull affects the oceans on Earth, as the Moon pulls water towards it, causing a change in the tides.

No longer able to resist gravity’s tug as its orbit dwindled, the spherical lander — an estimated 3 feet (1 meter) across — was the last part of the spacecraft to come down.

A temporary “mini-moon” will whirl around Earth for about two months as our planet’s gravity captures a small asteroid named 2024 PT5 in its orbit.
