TL;DR

A new high-resolution map of distant galaxies has been created using NASA's James Webb Space Telescope.
The map is the most detailed yet over a large patch of sky and has twice the resolution of previous Hubble Space Telescope attempts.
Scientists study dark matter indirectly by observing how its gravity warps light from distant galaxies.
The map shows galaxy clusters and the strands of dark matter connecting them, helping to visualize the universe's skeleton.
