“Terra Incognito” –‘Ghost Galaxies’ of a Great Wall Discovered Hidden Beyond the Milky Way


South Pole Wall


A ‘Holy Grail’ of astronomy is to provide a clear map of our galaxy –a perspective of Earth’s relationship to the physical universe where our solar system drifts between two spiral arms at its outer edges of the Milky Way, some 27,000 light-years from its opaque central disk. Beyond that, like the maps of ancient sea-faring mariners, is a terra ingognito, the “zone of avoidance” where no space craft has yet to ever travel beyond the opaque central disk.
