The same elastic scattering processes cause the sky to be blue. The polarization is characterized at each wavelength by its degree of polarization, and orientation (the e-vector angle, or scattering angle). The polarization pattern of the sky is dependent on the celestial position of the Sun. While all scattered light is polarized to some ...
The blue sky spectrum contains light at all visible wavelengths with a broad maximum around 450–485 nm, the wavelengths of the color blue. Diffuse sky radiation is solar radiation reaching the Earth 's surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere .
In a technique known as blue field entoptoscopy, the effect is used to estimate the blood flow in the retinal capillaries.The patient is alternatingly shown blue light and a computer generated picture of moving dots; by adjusting the speed and density of these dots, the patient tries to match the computer generated picture to the perceived entoptic dots.

Two other effects which occurred between reionization and our observations of the cosmic microwave background, and which appear to cause anisotropies, are the Sunyaev–Zeldovich effect, where a cloud of high-energy electrons scatters the radiation, transferring some of its energy to the CMB photons, and the Sachs–Wolfe effect, which causes ...
Super Mario Clouds is an installation artwork based on a hardware modification to a Super Mario Bros. game cartridge.The mod removes visual assets from the Nintendo Entertainment System game, removing the mushrooms, grasses, and protagonist (), and leaving just the blue sky and its white clouds.
Google Sky is a feature that was introduced in Google Earth 4.2 on August 22, 2007, in a browser-based application on March 13, 2008, [40] and to Android smartphones, with augmented reality features. Google Sky allows users to view stars and other celestial bodies. [ 41 ]
