James Webb telescope discovers 'Cosmic Vine' of 20 connected galaxies sprawling through the early...

Astronomers using James Webb Space Telescope (JWST) data have discovered a massive chain of at least 20 closely packed galaxies from the early universe, and it could reveal insight into how the most massive structures in the cosmos form.
This megastructure — nicknamed the "Cosmic Vine" in a study published Nov. 8 to the preprint database arXiv — swoops through space in a bow shape, estimated to stretch more than 13 million light-years long and about 650,000 light-years wide.
