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 ...

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 ...

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 ...
