Combining the images from all EPIC cameras, the Lockman Hole provides the deepest ever X-ray survey of this region where observation of the early Universe is facilitated by the relative absence of intervening, absorbing material. The view gives a 'real colour' representation of all the sources, coded according to their X-ray hardness. More than 60 new sources are detected in the 5-10 keV band alone. Image courtesy of G.
