The deepest LOFAR image ever made, in the region of sky known as ‘Elais-N1’, which is one of the three fields studied as part of this deep radio survey. The image arises from a single LOFAR pointing observed repeatedly for a total of 164 hours. Over 80,000 radio sources are detected; this includes some spectacular large-scale emission arising from massive black holes, but most sources are distant galaxies like the Milky Way, forming their stars (see insets).
