Hubble's Deepest View of Universe Unveils Never-Before-Seen
Galaxies The new Wide Field Camera 3 aboard the NASA/ESA Hubble
Space Telescope has taken the deepest image yet of the Universe
in near-infrared light. The faintest and reddest objects in the
image are likely the oldest galaxies ever identified, having
formed between only 600–900 million years after the Big Bang. In
2004, Hubble created the Hubble Ultra Deep Field (HUDF), the
deepest visible-light image of the Universe, and now, with its
brand-new camera, Hubble is seeing even farther. This image was
taken in the same region as the visible HUDF, but is taken at
longer wavelengths. Hubble’s newly installed Wide Field Camera 3
(WFC3) collects light from near-infrared wavelengths and
therefore looks even farther back towards the Big Bang, because
the light from hot young stars in these 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. This new de
