NASA's Hubble Space Telescope has made the deepest image of the universe ever taken in near-infrared light. The
faintest and reddest objects in the image are galaxies that formed 600 million years after the Big Bang. No galaxies have
been seen before at such early times. The new deep view also provides insights into how galaxies grew in their formative
years early in the universe's history.
The image was taken in the same region as the Hubble Ultra Deep Field (HUDF), which was taken 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.
The photo was taken with the new WFC3/IR camera on Hubble in late August 2009 during a total of four days of pointing
for 173,000 seconds of total exposure time. Infrared light is invisible and therefore does not have colors that can be
perceived by the human eye. The colors in the image are assigned comparatively short, medium, and long, near-infrared
wavelengths (blue, 1.05 microns; green, 1.25 microns; red, 1.6 microns). The representation is "natural" in that blue
objects look blue and red objects look red. The faintest objects are about one-billionth as bright as can be seen with the
These Hubble observations are trailblazing a path for Hubble's successor, the James Webb Space Telescope (JWST),
which will look even farther into the universe than Hubble, at infrared wavelengths. The JWST is planned to be launched
