Brave New World is about to hit cinemas, bringing with it the gamma-ray-powered Red Hulk. Here's what you need to know about ...

RCW 38 lies approximately 5,500 light-years away in the constellation Vela. Unlike many star clusters that appear as simple ...

The European Southern Observatory (ESO) has released a stunning 80 million-pixel image of the star cluster RCW 38, as captured by ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA), ...

Thus the burst area continues to glow with electro-magnetic waves—not gamma rays any more, but less energetic x-rays—and then the even less energetic wavelengths of visible light. This visible ...

Researchers at the University of Pennsylvania are developing a robot with an advanced radio-based sensing system that could ...

Bluetooth uses radio waves because radio waves pass through walls but the signal is weakened on doing so. Optical fibres (visible light to infrared) are used for cable television and high-speed ...

The explosions release ionizing radiation that reaches the Earth ... This is in part because visible light from solar flares can disrupt the circadian rhythm, which can in turn affect heart ...

For example, a nonlinear material can turn visible light into ultraviolet radiation, which is of a different frequency range. This frequency upconversion capability, combined with the inherent ...
