Following the 3,000th orbit of NASA's AWE (Atmospheric Waves Experiment) aboard the International Space Station, researchers ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Gravity, or gravitational attraction ... backward with respect to their normal orbits. This offended some astronomers' sense of cosmos, the orderliness of the universe. In a universe perfectly ...

Following the 3,000th orbit of NASA's AWE (Atmospheric Waves Experiment) aboard the International Space Station, researchers publicly released the ...

Hollywood films would have us believe the best way to deal with an Earth-threatening asteroid is to blast it out of orbit. But the European Space Agency (ESA) is looking at a far subtler approach to ...

The gravity well is a hands-on tool for visualizing gravity, orbits, and spacetime curvature. It helps students understand how massive objects (like planets and stars) warp space, causing smaller ...

Gravity also holds Earth and the other planets in their orbits around the Sun. The force of gravity also exists on the Moon but it is not as strong as it is on Earth. This is because the Moon is ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. A new recipe for gravity could help ...

Barnard's Star is a small, dim star, of the type that astronomers call red dwarfs. Consequently, even though it is one of the ...
