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 ...
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.
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 .
The ice crystals responsible for halos are typically suspended in cirrus or cirrostratus clouds in the upper troposphere (5–10 km (3.1–6.2 mi)), but in cold weather they can also float near the ground, in which case they are referred to as diamond dust. The particular shape and orientation of the crystals are responsible for the type of ...
The equipment allows the rover to take images that would show scientists how cloud particles glow over time. To create the panorama you see above, NASA stitched together 28 images taken by the ...
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 ...
Cirrostratus nebulosus are formed by gently rising air. The cloud is often hard to see unless the sun shines through it at the correct angle, forming a halo. [4] While usually very light, the cloud may also be very dense, and the exact appearance of the cloud can vary from one formation to another. [5]
