Definition: reddening: The phenomenon of the trailing hemisphere of a planetary body being darker at shorter wavelengths ("redder") than the leading hemisphere.
The reddening of an object is inversely proportional to the wavelength of optical light, so shorter wavelengths (blue) are more heavily reddened than longer (red) wavelengths.

Reddening may be determined by finding pairs of lines which are far apart in wavelength but have line ratios fixed by atomic physics.
Reddening
The process by which light from an astronomical object grows red as the light travels through interstellar dust. Dust scatters blue light more than red, thus leaving predominantly red light transmitted.
Red Dwarf ...
reddening Dimming of starlight by interstellar matter, which tends to scatter high-frequency (blue) components of the radiation more efficiently than the lower-frequency (red) components.
reddening - (n.)
The phenomenon by which the extinction of blue light by interstellar matter is greater than the extinction of red light so that the redder part of the continuous spectrum is enhanced.

The reddening of light from a very massive object caused by photons escaping and traveling away from the object's strong gravitational field. An example of gravitational redshift is light escaping from the surface of a neutron star.

The reddening of the skin due to the action of sunlight depends both on the amount of sunlight and on the sensitivity of the skin ("erythemal action spectrum") over the UV spectrum.
The reddening of starlight in passing through fine particles of interstellar dust. [H76]

Interstellar Reddening: As light from a star travels through interstellar space it encounters some amount of dust. This dust scatters some of the light, preferentially the short wavelength (blue) components.
Interstellar Reddening - The obscuration, by interstellar dust particles, of blue starlight more strongly than red starlight

Interstellar Reddening
The process in which dust scatters blue light out of starlight and makes the stars look redder than they actually are.

space reddening The observed reddening, or absorption of shorter wavelengths, of the light from distant celestial bodies due to scattering by small particles in interstellar space. Compare red shift. space simulator 1.

Our Milky Way galaxy, like most spiral galaxies, is filled with dust.

Compare space reddening.
The term red shift is applied both to the Doppler effect caused by the relative speed of recession of the observed body and the gravitational or relativistic shift in which the frequency of light emitted by atoms in stellar ...
This preference for dust to scatter short wavelength light causes another effect known as interstellar reddening.
"ESO were looking for a demonstration of the reddening towards the cluster, which is very large - something like 12 magnitudes in the V-band," says Howes, ...
The ISM is also responsible for extinction and reddening, the decreasing light intensity and shift in the dominant observable wavelengths of light from a star.
Dust is responsible for the interstellar reddening and extinction of starlight.

The Sun's magnitude at noon is about -26.7, but at the horizon, it would only be in the order of -15.8, a loss of brilliance almost 23,000x from that of noon. In addition, reddening would be very prominent.
REFRACTION ...
Dust blocks visible light causing interstellar extinction and scatters incident starlight, particularly blue light (which has a wavelength comparable to the dust grain's size), causing reddening.
Since the distances and intrinsic luminosities of many stars are estimated from analysis of their spectra, this effect, called interstellar reddening, has been responsible for errors in calculating the distances and luminosities of these stars.
