Madre de Dios!

Hubble infrared photo of extraordinarily dense cluster of galaxies Abell 68, which is 2.1 Billion light years away. This is a leit motiv in the Cosmos, which is mostly emptiness studded with roughly spherical accumulations of matter here and there--planets, suns, star clusters, galaxies and clusters of galaxies. Magnificent.
