Cornell University researchers have demonstrated that acoustic sound waves can be used to control the motion of an electron as it orbits a lattice defect in a diamond, a technique that can potentially ...

The orbits of the planets around the sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since ...

The very definition of a crystal relies on the notion of symmetry: the atoms line up in highly ordered, repeating honeycomb patterns, and that symmetry should be evident whichever way you look at it.

When Johannes Kepler made the intuitive leap in the early 1600s to realize that planetary orbits were not circular, as they had been assumed to be for millennia, he stuck to the trusty ellipse. Indeed ...

For almost a decade, thanks to an increased effort in exoplanet hunting such as NASA's Kepler mission, astronomers have identified a lot of Earth-like planets outside our solar system. However, they ...

Earth is on an orderly path around the sun, orbiting in nearly the same plane as our star’s equator. In 2008, however, astronomers began finding worlds in other solar systems that sail far above and ...
