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 ...

Optical illusions are fascinating visual phenomena that trick the brain into seeing something that isn’t actually there or perceiving an image differently than reality. These illusions play with light ...

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 ...

Believe it or not, we've seen a few optical illusions in space over the year. Well, we haven't seen them – the Hubble ...

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 ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

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

Researchers will soon be able to study biological changes at scales and speeds not previously possible to significantly expand knowledge in areas such as disease progression and drug delivery.

The NASA James Webb Space Telescope captured a stunning image of an Einstein ring, an optical phenomenon created by gravitational lensing. This rare sight, caused by light from a distant galaxy ...
