Stitching together a cosmic crochet⁣ ⁣ Using NASAWebb, astronomers have discovered a thread-like arrangement of 10 galaxies that existed just 830 million years after the big bang. (You can see the 10 galaxies marked by 8 circles in the fourth image. Two of the circles contain more than one galaxy.) The 3 million light-year-long structure is anchored by a luminous quasar – a galaxy with an active, supermassive black hole at its core. The team believes the filament will eventually evolve into a massive cluster of galaxies, much like the well-known Coma Cluster in the nearby universe.⁣ ⁣ Galaxies run in packs. They gather not only into clusters, but into vast interconnected filamentary structures with gigantic barren voids in between. A “cosmic web” of sorts, which started out subtle but grew more distinct over time as gravity drew matter together. The discovery is from Webb's ASPIRE science program, whose main goal is to study the cosmic environments of the earliest black holes. In total...
