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

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 challenge our brains, making us perceive things differently. Readers are given five seconds to find the ...

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 ...

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