What it is

A region with no bright galaxies, one of the 25 voids within 80 million light-years that Pustilnik et al. (2019) mapped over the whole sky, walled by galaxies brighter than absolute K magnitude −22. It is a cluster of overlapping empty spheres, drawn as the ellipsoid spanning its extent along the supergalactic axes.
