Hubble's latest image is another stunner: a new version of the Ultra Deep Field – this time in near-infrared light and taken with the newly installed Wide Field Camera 3.

This image was taken in the same region as the visible Ultra Deep Field in 2004, but this new deep view at longer wavelengths provides insights into how galaxies grew in their formative years early in the Universe's history.
