This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

Physics is often about recognizing patterns, sometimes repeated across vastly different scales. For instance, moons orbit planets in the same way planets orbit stars, which in turn orbit the center of ...

Planetary scientists have proposed a solution to the centuries-old problem of why the Moon’s far side bulges at its equator. Ian Garrick-Bethell and colleagues at the Massachusetts Institute of ...

Close companions can influence stellar evolution in many ways. While some companions can be detected around young stellar ...

Flash Physics is our daily pick of the latest need-to-know developments from the global physics community selected by Physics World‘s team of editors and reporters Close call: artist's impression of ...

In our Solar System, the planetary orbits all have a similar orientation. Their orbital planes vary by a few degrees, but roughly the planets all orbit in the same direction. This invariable plane, as ...

EmDrive is back in the news. Someone finally decided to put the so-called "impossible space engine" to the test in orbit. This is the engine that doesn't use any propellant but seems to generate small ...

Hey, physicists and materials scientists: You'd better reevaluate your work if you study iridium-based materials -- members of the platinum family -- when they are ultra-thin. Iridium 'loses its ...
