By tracing solar flare gamma rays, scientists gain new insight into particle behavior that shapes space weather forecasts.

It might be true that there's an ultimate speed limit to everything in the Universe — the speed of light in a vacuum — but that doesn't mean there's a limit to how energetic a single particle can be.

WASHINGTON — One of the enduring sci-fi moments of the big screen — R2-D2 beaming a 3-D image of Princess Leia into thin air in “Star Wars” — is closer to reality, thanks to the smallest of screens: ...

Space is not empty. It contains very tenuous gases, plasmas, and various types of radiation, like light, infrared, ultraviolet, X rays, etc. As you note, we’re measuring the average speed of randomly ...

Researchers at the Centre for Nano Science and Engineering (CeNSE), IISc, have developed a technique to trap and move nano-sized particles in a fluidic medium using only light. The nanotweezer ...

In the supplemental material the experimental setup is shown (see top image), which is designed to make the individual iron-coated polymer particles rotate. The particles are called Janus particles ...

Researchers report that nonlocality is a universal property of the world, regardless of how and at what speed quantum particles move. The phenomenon of quantum nonlocality defies our everyday ...

The hyperdrive from Star Wars appears to depict an ultra-relativistic motion through space, extremely close to the speed of light. Under the laws of relativity, you neither reach nor exceed the speed ...
