In the case of HAT-P-7b the effect was reversed – that is, the redshifted light appeared bluer, then the blueshifted light appeared redder, making it apparent that the orbit of the planet was not in the same direction of that of HAT-P-7.

Infrared astronomy is traditionally described as focusing on the "old, cold and dusty" - that is, the redshifted light from ancient galaxies on the edge of the observable universe, cool objects such as brown dwarfs that shine only in infrared wavelengths, and infant stars and planets still wrapped in shrouds of dust. launched last May, is the most sensitive far-infrared telescope in operation.

The Keck 10-m telescope in Hawaii, the 6. 5-m Magellan telescope in Chile, and the MMT telescope in Arizona rapidly focused on the new star, revealing that the wavelengths of light emitted from the supernova were stretched or 'redshifted' by 80 percent due to the expansion of the universe.

If the light had been stretched, or 'redshifted', through the Doppler effect - the same distorting effect that causes an ambulance siren to rise in pitch when approaching or drop as it recedes - it could only mean one thing: everything in the universe was hurtling away from our humble Milky Way, and the further away it was, the faster it fled.

For the large angular-scale fluctuations, the denser regions redshifted the light climbing out of those regions, and therefore produce cooler spots in the CMBR; in contrast, for the small angular-scale fluctuations, denser regions were regions where the plasma was hotter, hence these denser regions produce hotter spots in the CMBR.

Light traveling a given distance is redshifted by less than it would be if the whole universe expanded at our local rate.

avivamagnolia commented on the word redshifted
~change in the wavelength of light, in which the wavelength is longer than when it was emitted at the source
~shift toward longer wavelengths of the spectral lines emitted by a celestial object that is caused by the object moving away from the earth.
~shift in the spectra of very distant galaxies toward longer wavelengths (toward the red end of the spectrum); generally interpreted as evidence that the universe is expanding
~displacement of the spectrum of a celestial body toward longer wavelengths that is a consequence of the Doppler effect or the gravitational field of the source
~measurement of a celestial body's redshift equal to the ratio of the displacement of a spectral line to its known unshifted wavelength and used especially to calculate the body's distance from earth
