An invisible cosmic bridge

By Stephen Ornes / July 23, 2012
It’s impossible to see with the naked eye, but astronomers say a bridge made of dark matter connects two galaxy clusters. This picture shows hot gas around and between the two clusters, Abell 222 (blob at top) and Abell 223 (bottom blob). The yellow is the hottest part of the gas, where the galaxies reside, and the red is cooler. Credit: ESA/ XMM-Newton/ EPIC/ ESO (J. Dietrich)/ SRON (N. Werner)/ MPE (A. Finoguenov)
