ISS microgravity experiments reveal how particles cluster, helping science on Earth and future space missions.

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Russia has quietly taken a science fiction staple and turned it into a legal blueprint, securing a patent for a rotating ...

Monisha Ravisetti was a science writer at CNET. She covered climate change, space rockets, mathematical puzzles, dinosaur bones, black holes, supernovas, and sometimes, the drama of philosophical ...

Artificial gravity remains the stuff of science fiction. But dealing with microgravity causes significant problems in many astronauts, ranging from bone deterioration to loss of sight. An alternative ...

The Juno spacecraft now orbiting Jupiter has a suite of science instruments which will investigate the existence of a possible solid planetary core, map Jupiter’s intense magnetic field, measure the ...

In the April 1981 issue of Popular Science, we explored the many initiatives and techniques used in the exciting hunt for sensing gravity waves, then out of reach. By Bill Gourgey Published May 18, ...

The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...
