  2. Atmospheric refraction - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_refraction

    Atmospheric refraction distorting the Sun’s disk into an uneven shape as it sets in the lower horizon. Astronomical refraction deals with the angular position of celestial bodies, their appearance as a point source, and through differential refraction, the shape of extended bodies such as the Sun and Moon.

  3. Mirage of astronomical objects - Wikipedia

    en.wikipedia.org/wiki/Mirage_of_astronomical_objects

    10.12 Then spoke Joshua to the LORD in the day when the LORD delivered up the Amorites before the children of Israel; and he said in the sight of Israel: 'Sun, stand thou still upon Gibeon; and thou, Moon, in the valley of Aijalon. 10.13 And the sun stood still, and the moon stayed, until the nation had avenged themselves of their enemies.

  4. Moonrise and moonset - Wikipedia

    en.wikipedia.org/wiki/Moonrise_and_moonset

    Atmospheric distortion of the Moon's appearance at Earth's horizon. The Moon appears to be larger at moonrise or moonset due to an illusion. This illusion, known as the Moon illusion, is caused by an effect of the brain. There is no definitive explanation for the Moon illusion.

  5. Corona (optical phenomenon) - Wikipedia

    en.wikipedia.org/wiki/Corona_(optical_phenomenon)

    Lunar corona A solar corona up Beinn Mhòr (South Uist). In meteorology, a corona (plural coronae) is an optical phenomenon produced by the diffraction of sunlight or moonlight (or, occasionally, bright starlight or planetlight) [1] by individual small water droplets and sometimes tiny ice crystals of a cloud or on a foggy glass surface.

  6. Astronomical seeing - Wikipedia

    en.wikipedia.org/wiki/Astronomical_seeing

    In astronomy, seeing is the degradation of the image of an astronomical object due to turbulence in the atmosphere of Earth that may become visible as blurring, twinkling or variable distortion. The origin of this effect is rapidly changing variations of the optical refractive index along the light path from the object to the detector.

  7. Moon illusion - Wikipedia

    en.wikipedia.org/wiki/Moon_illusion

    The Moon looks larger near distant buildings than nearby ones in this simulated skyline. The size of a viewed object can be measured objectively either as an angular size (the visual angle that it subtends at the eye, corresponding to the proportion of the visual field that it occupies), or as physical size (its real size measured in, say, meters).

    The NASA astronauts who became the first people to land on the moon's surface in the 1960s and 1970s also discovered a previously unknown lunar characteristic - it has an atmosphere, though quite ...

  9. Atmospheric diffraction - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_diffraction

    The Moon is seen through thin vaporous clouds, which glow with a bright disk surrounded by an illuminated red ring. A longer exposure would show more faint colors beyond the outside red ring. Another form of atmospheric diffraction or bending of light occurs when light moves through fine layers of particulate dust trapped primarily in the ...
