The two movies below show a 3D Map of the nearby Universe, where we take successive slices. The volume we have mapped is roughly circular, so its a bit like slicing an orange vertically from the edge through to the opposite edge. The location of our Milky Way Galaxy is in centre of the middle frame (marked SGZ=0) halfway through the movie. The map spans nearly two billion light year from side to side. Regions with many galaxies are shown in white or red, whereas regions with fewer galaxies are dark blue.

This movie is based on the work presented in Carrick et al. (ADS, MNRAS, arXiV).
