Iridescence is therefore mostly seen at cloud edges or in semi-transparent clouds, while newly forming clouds produce the brightest and most colorful iridescence. When the particles in a thin cloud are very similar in size over a large extent, the iridescence takes on the structured form of a corona , a bright circular disk around the Sun or ...
Iridescence (also known as goniochromism) is the phenomenon of certain surfaces that appear gradually to change colour as the angle of view or the angle of illumination changes. Iridescence is caused by wave interference of light in microstructures or thin films .
If you’ve ever indulged in the habit of cloudspotting, you’ve probably seen all kinds of things in the sky, from animals and faces to UFOs and cartoon characters. But did you know that our ...
An occurrence of altocumulus and cirrocumulus cloud iridescence Sunset reflecting shades of pink onto grey stratocumulus clouds. The color of a cloud, as seen from the Earth, tells much about what is going on inside the cloud. Dense deep tropospheric clouds exhibit a high reflectance (70% to 95%) throughout the visible spectrum.
Mammatus clouds filled the sky over Bucks County on Sunday night, June 30, 2024, giving a treat of orange and pink fluffy clouds and filling social media with the spectacular sky.
Circumhorizontal arcs, especially when only fragments can be seen, are sometimes confused with cloud iridescence. This phenomenon also causes clouds to appear multi-coloured, but it originates from diffraction (typically by liquid water droplets or ice crystals) rather than refraction. The two phenomena can be distinguished by several features.
Mars clouds are seasonal and rare, but Curiosity caught some colorful early wisps that seem to be made of carbon dioxide "dry ice" rather than water. NASA's Curiosity rover captured rare photos of ...
A pileus (/ ˈ p aɪ l i ə s /; Latin for 'cap'), also called scarf cloud or cap cloud, is a small, horizontal, lenticular cloud appearing above a cumulus or cumulonimbus cloud. Pileus clouds are often short-lived, appearing for typically only a few minutes, [ 1 ] with the main cloud beneath them rising through convection to absorb them.
