While one eye of Hubble was observing its main target, the massive galaxy cluster Abell 370, the second eye – another instrument – was looking at a part of the sky right next to the cluster.
Although not as spectacular as the light-bending clusters, these parallel fields are as deep as the main images and can even compete with the famous Hubble Deep Field as regards depth. They are therefore a valuable tool for studying the evolution of galaxies from the early epochs of the Universe until today.
