#Astronomers using the #JamesWebbSpaceTelescope have discovered a thread-like arrangement of 10 #galaxies that existed just 830 million years after the Big Bang. The 3 million light-year-long structure is anchored by a luminous #quasar—a galaxy with an active, #supermassiveblackhole at its core. The team believes the filament will eventually evolve into a massive #clusterofgalaxies, much like the well-known #ComaCluster in the #nearbyuniverse.

Webb identifies the earliest strands of the cosmic web

Galaxies are not scattered randomly across the universe. They gather together not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. This "cosmic web" started out tenuous and became more distinct over time as gravity drew matter together.

Astronomers witness the birth of a very distant cluster of galaxies from the early universe

Using the Atacama Large Millimeter/submillimeter Array (ALMA), of which ESO is a partner, astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy—the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the universe and this result, published today in Nature, further reveals just how early these structures begin to form.
