Universe is expanding/galaxies moving away from each other and far away galaxies are moving away from us faster. so the light is redshifted. .."at very large redshifts, much of the ultraviolet and visible light from distant sources is shifted into the infrared part of the spectrum. This means that infrared studies can give us much information about the ultraviolet and visible spectra of very young, distant galaxies" If some stars/galaxies are so red shifted that viewing infrared shows more -- why do some stars not "look red"? When my kids look at sky at night - stars all look cosmic latte. this question came up.... I can't figure this out, so I'm posting. thx!!
