The Sun has a weather pattern of its own, and one of the strangest is the solar rain that falls in its atmosphere during ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics.

Our eyes are tuned to only a tiny proportion of the electromagnetic spectrum, but it’s where the Sun is brightest.

"When you put it into context, Punctum is astonishingly bright." A bewilderingly powerful mystery object found in a nearby galaxy and only visible so far in millimeter radio wavelengths could be a ...

ABSTRACT: The original intention of the author’s preoccupation with the quantum-mechanical behaviour of simple atoms and molecules such as Hydrogen and Helium was, on the one hand, the elegant ...

Ultraviolet radiation, a high-frequency form of energy from the sun, is classified in the same risk category as X-rays and nuclear radiation. As temperatures and sun exposure increase, experts at the ...

"The planet seems to be triggering particularly energetic flares." Some planets take the expression "you're your own worst enemy" to the extreme. At least, that's what astronomers found when they ...

President Trump has said there is little he could do to stop the Israeli attacks. A European diplomatic effort to rein in the hostilities ended without a breakthrough on Friday. Follow our ongoing ...

Abstract: A two-layer planar surface-wave antenna (SWA) with directive gain exactly at endfire is proposed for applications including integration with solar panels, CubeSats, and other small ...

Programmable metasurfaces have emerged as a prominent research focus in the field of artificial electromagnetic materials. By integrating active components such as PIN diodes and implementing ...
