Controlling light at dimensions thousands of times smaller than the thickness of a human hair is one of the pillars of modern ...

An astronaut on the ISS photographed a "lunar halo" over the Indian Ocean, revealing ice and rare optical phenomena from ...

A new theory of "dark photons" attempted to explain a centuries-old experiment in a new way this year, in an effort to change ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light ...

With heat, humidity, and often heavy pollution, unusual optical phenomena are not uncommon in parts of Asia. But what was recently observed in China, in Chengdu near Sichuan, was truly extraordinary: ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

As nights have gotten brighter, the list of health problems linked to artificial lighting has gotten longer, from insomnia to cancer. Lighting in urban areas like Chicago (shown) has gotten brighter ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

IN discussing the effects of atmospheric refraction during solar eclipses Prof. Anderson disregards the shallowness of the effective layer of air as compared with the diameter of the moon's shadow.
