Objects in mirror may be more infrared than they appear.
far away, the light they emit gets stretched out, going from visible to infrared, a phenomenon called, Alice Shapley, an astronomy professor at UCLA explained to me. This happens because the universe is expanding. The Carina nebula is within our home galaxy, so it’s not far away enough to get redshifted. But many galaxies in the deep field image are far away enough that the light they emit does get redshifted, leaving scientists to translate it back into a form that our eyes can understand.
To make the images circulating now, Shapley explained, the JWST used its infrared cameras to collect several “brightness images” in grayscale. Six filters each captured different wavelengths of infrared light. Back on Earth, each filter was assigned a color. The filter capturing the longest wavelength was red; the filter capturing the shortest wavelength was blue, with the other colors in between.
