Abell 222 is a giant group of galaxies in deep space. So is Abell 223 — one of Abell 222’s nearest neighbors. Each galaxy in each group is home to a massive number of stars, which means the clusters are brimming with light. But if you peer through a telescope at the space between the two galaxy clusters, you won’t see anything, just a dark patch of sky. The scenery would be the same if you could ride a spaceship from one group of galaxies to the other.
The space between the two galaxy clusters is, however, anything but empty, according to a new study by astronomers.
