Bridge of gas connecting galaxies. Composite image showing a bridge of hot gas (orange) that connects galaxy clusters Abell 399 (lower centre) and Abell 401 (top left). This galaxy pair is located about a billion light-years from Earth,and the gas bridge extends approximately 10 million light-years between them. This image shows the two galaxy clusters as seen at optical wavelengths with ground-based telescopes and through the Sunyaev-Zel'dovich effect (orange) with the Planck space telescope | |
