Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean, while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [1]
Mie scattering is responsible for the light scattered by clouds, and also for the daytime halo of white light around the Sun (forward scattering of white light). [6] [7] [8] Sunset colors are typically more brilliant than sunrise colors, because the evening air contains more particles than morning air.
Before answering why the sky is purple, here's a quick rundown as to why the sky is blue. The sun emits shortwave radiation on the visible light spectrum, and in a process called Rayleigh ...
Purple sky on the La Silla Observatory. [16] The sky can turn a multitude of colors such as red, orange, pink and yellow (especially near sunset or sunrise) and black at night. Scattering effects also partially polarize light from the sky, most pronounced at an angle 90° from the Sun.

The Purple Earth Hypothesis (PEH) is an astrobiological hypothesis, first proposed by molecular biologist Shiladitya DasSarma in 2007, [1] that the earliest photosynthetic life forms of Early Earth were based on the simpler molecule retinal rather than the more complex porphyrin-based chlorophyll, making the surface biosphere appear purplish ...
The Sun is a G-type main-sequence star (G2V) based on spectral class, and it is informally designated as a yellow dwarf because its visible radiation is most intense in the yellow-green portion of the spectrum. It is actually white, but from the Earth's surface, it appears yellow because of atmospheric scattering of blue light. [9]
The sun may too bright and too powerful for us to look at with the naked eye, even from nearly 92 million miles away on Earth, but a solar orbiter recently got an unprecedented up-close glimpse of ...
