The Sun is not nailed to the center of the solar system. It moves, wobbles, and traces a small loop through space, tugged by ...

A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes far below reshape the planet's gravity field over millions of years.

Gravity may seem constant, but it actually varies across the planet—and one of the strangest places is Antarctica, where gravity is slightly weaker than expected. Scientists have traced this “gravity ...

The “gravity hole” in East Antarctica formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our oceans.

Astronomers have discovered a rare lemon-shaped planet called PSR J2322-2650b orbiting a city-size star. Found using NASA’s James Webb Space Telescope, the Jupiter-size world is stretched by extreme ...

Travel to another moon or planet and your weight will change — but not your mass. This is because your weight on other worlds depends on the gravitational force of attraction between you and that ...

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it — very, very carefully. This is ...

Isaac Newton was an English polymath who excelled in many fields, including arithmetic, physics, astronomy, alchemy, religion, writing, and invention. His work influenced how people thought about the ...
