A vast spider’s web of matter is thought to stretch across the whole universe and astronomers have just got the best view of it yet.
Hideki Umehata at the RIKEN institute in Japan and his colleagues used the Very Large Telescope (VLT) in Chile to observe a young cluster of galaxies 12 billion light years from Earth, called SSA22. Peering into the cluster, they spotted wispy filaments of hydrogen gas spanning the space between the galaxies. These seem to be filaments of the long-theorised cosmic web.
