DESI slice (IMAGE) Ohio University Caption This small slice of DESI data has Earth on the left and looks back in time to the right. Every dot represents a galaxy (blue) or quasar (red). The farther to the right an object is, the farther away it is. The upper wedge includes objects all the way back to about 12 billion years ago. The bottom wedge zooms in on the closer galaxies in more detail. The clumps, strands, and blank spots are real structures in the universe, showing how galaxies group together or leave voids on gigantic scales.
