The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

This channel electron multiplier amplifies the faint signals generated in some types of mass spectrometry and other precision analytical techniques. Electrons are focused into the curved device, where ...

I took a deep dive into the photoelectric effect — where light hits a surface and kicks electrons out. It’s simple, ...

PhoSim simulates the atmosphere, including air turbulence, as well as distortions from the shape of the telescope’s mirrors and the electrical properties of the sensors. The photons are propagated ...

The Large Hadron Collider is one of the biggest experiments in history, but it’s also one of the hardest to interpret. Unlike ...

From the International Space Station, NASA astronaut Nichole Ayers captured a rare red sprite over Mexico and the United ...

A picture snapped from the International Space Station (ISS) by NASA astronaut Nichole Ayers has captured a lesser-seen view ...

A new method in electron microscopy enables sub-20-picometer targeting of individual atoms without prior exposure, opening ...

At the summit of Cerro Pachón, the Vera C. Rubin Observatory has started its work.

NASA has released the closest-ever photos of the sun, taken by the Parker Solar Probe at just 3.8 million miles (6.1 million kilometers) from the star's surface. The new images reveal important ...

Plus, microwaves are appliances that the FDA strictly regulates to reduce any potential risk of radiation leakage; the agency ...
