New Hubble Ultra Deep Field

In didn’t take long for the folks at STSci to use the rehab’d Hubble to take another ultra deep field image. This one uses the infrared capabilities and shows galaxies that are 13 billion years distant in look-back time. The image was created using 3 different infrared wavelengths and assigning them the colors red, green and blue. The most distant galaxies are smaller than the Milky Way and are intrinsically blue.
