Description

With its brand-new camera, Hubble is seeing even farther than its 2004 deepest visible-light image of the Universe in the same region. Hubble's newly installed Wide Field Camera 3 (WFC3) collects light from near-infrared wavelengths and therefore looks even deeper, because the light from hot young stars in 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 new deep view also provides insights into how galaxies grew in their formative years early in the Universe's history.

This image was taken with the new WFC3/IR camera on Hubble in late August 2009 during a total of four days of pointing for 173000 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 naked eye. The image is roughly 2.4 arcminutes wide.
