Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength ...

Such virtual unrolling is a two-stage process pioneered by W. Brent Seales, a computer scientist at the University of Kentucky.

A remarkable aspect of this technology is its ability to project entirely different images depending on both the wavelength (color) and spin (polarization direction) of light. For example, ...

But when scientists peer very far back, they find conundrums. JWST observations of the distant past are at odds with ...

A binary system 18,000 light-years away, emits X-rays as a Sun-like star orbits a dense companion, either a neutron star or black hole. Telescopes like Chandra, IXPE, and XMM-Newton capture its ...

Among the wreckage of the Milky Way — where the violent deaths of stars usually leave chaos and crumpled shells — astronomers ...

Analyzing massive datasets from nuclear physics experiments can take hours or days to process, but researchers are working to radically reduce that time to mere seconds using special software being ...

The science team behind Perseverance wanted to know whether that glow from the Mars aurora could be seen in the visible spectrum.

Abstract: Nighttime light (NTL) remote sensing data have been widely used in various fields ... this article takes the Sustainable Development Goals Science Satellite 1 (SDGSAT-1) NTL image of Beijing ...

Light is all around us, essential for one of our primary senses (sight) as well as life on Earth itself. It underpins many ...

On Earth, auroras form when solar particles interact with the global magnetic field, funneling them to the poles where they collide with atmospheric gases and emit light. The most common color ...

Have you ever had an X-ray taken of your bones? Well, so has the Milky Way. NASA's Chandra X-ray Observatory regularly images our home galaxy, and a recent scan caught something that might be familiar ...
