The 22° Halo is a striking optical phenomenon that manifests as a circular ring of light around the sun or moon. This halo is formed by the refraction of light through ice crystals in high ...

Think you have the vision of a true legend? This mind-bending optical illusion hides a sneaky cat within the image, but only ...

Solar horns, also known as Devil's horns, refer to the crescent-shaped parts of the Sun that remain visible during a partial ...

Some optical phenomena depend on the quantum nature of light and the interaction of light with matter. Geometric optics and physical optics are models that describe phenomena while ignoring properties ...

This research uncovers remarkable quantum optical phenomena which may enhance quantum technology and paves the road for an exciting nascent field: four-dimensional quantum optics. A new study from ...

Physicists at the University of Ottawa add an orbital spin to their laser beams to control the movement of electrons in their ...

That's called a sun pillar. According to the National Weather Service, the optical phenomenon appears as a vertical shaft of light, visible most often at sunrise or sundown. SEE ALSO: Sunshine and ...

Researchers will soon be able to study biological changes at scales and speeds not previously possible to significantly ...

This approach offers a path toward realizing smaller, faster components for next-generation computers by taking advantage of an optical phenomenon called "intrinsic optical bistability." ...
