Diffuse sky radiation. In Earth's atmosphere, the dominant scattering efficiency of blue light is compared to red or green light. Scattering and absorption are major causes of the attenuation of sunlight radiation by the atmosphere. During broad daylight, the sky is blue due to Rayleigh scattering, while around sunrise or sunset, and especially ...
The blue field entoptic phenomenon is an entoptic phenomenon characterized by the appearance of tiny bright dots (nicknamed blue-sky sprites) moving quickly along undulating pathways in the visual field, especially when looking into bright blue light such as the sky. [ 1] The dots are short-lived, visible for about one second or less, and ...
Rayleigh scattering causes the blue color of the daytime sky and the reddening of the Sun at sunset. Rayleigh scattering ( / ˈreɪli / RAY-lee) is the predominantly elastic scattering of light, or other electromagnetic radiation, by particles with a size much smaller than the wavelength of the radiation. For light frequencies well below the ...
Entoptic phenomena (from Ancient Greek ἐντός (entós) 'within' and ὀπτικός (optikós) 'visual') are visual effects whose source is within the human eye itself. (Occasionally, these are called entopic phenomena, which is probably a typographical mistake.) In Helmholtz 's words: "Under suitable conditions light falling on the eye ...
Brenda Blue asks Jay Jay to take care of her dog, King, while she goes away on business, and Jay Jay tries to prove himself responsible while doing so. But when he eventually loses King by leaving him to play a game of Sky Tag, he soon learns from Big Jake that everyone makes mistakes, and telling someone is a way of being responsible.
The Three-Body Problem ( Chinese: 三体; lit. 'three body') is a 2008 novel by the Chinese science fiction author Liu Cixin. It is the first novel in the Remembrance of Earth's Past trilogy. [ 1] The series portrays a fictional past, present, and future wherein Earth encounters an alien civilization from a nearby system of three Sun-like stars ...
Cosmic ray visual phenomena, or light flashes ( LF ), also known as Astronaut's Eye, are spontaneous flashes of light visually perceived by some astronauts outside the magnetosphere of the Earth, such as during the Apollo program. While LF may be the result of actual photons of visible light being sensed by the retina, [1] the LF discussed here ...
