NASA’s Hubble Space Telescope has managed to capture the “deepest image” of the universe ever taken in near-infrared light.
The image was reportedly acquired in the same region as the Hubble Ultra Deep Field (HUDF), which was snapped in 2004 and is the deepest visible-light image of the universe.
“Hubble’s newly installed Wide Field Camera 3 (WFC3) collects light from near-infrared wavelengths and therefore looks even deeper into the universe, because the light from very distant galaxies is stretched out of the ultraviolet and visible regions of the spectrum into near-infrared wavelengths by the expansion of the universe,” NASA explained in a statement.
“The faintest and reddest objects seen in the image are galaxies that formed 600 million years after the Big Bang.”
Indeed, infrared light is invisible and therefore does not have colors that can be perceived by the human eye. As such, the colors in the image are assigned comparatively short, medium, and long, near-IR wavelengths (blue, 1.05 microns; green, 1.25 microns; red, 1.6 microns).
