Scientists have created the most detailed high-resolution map of distant galaxies to date, helping them study dark matter, the invisible substance that makes up over a quarter of the universe.

Using NASA’s James Webb Space Telescope, the map identified nearly 800,000 galaxies, including some seen for the first time, and captures structures spanning the past 10 billion years.

By observing how dark matter’s gravity bends light and connects galaxy clusters, researchers can trace its distribution and role in forming the universe’s “skeleton.”

The map offers twice the resolution of previous Hubble surveys and reveals new galaxy clusters and connecting dark matter strands, CBS News has reported.

Understanding these structures helps scientists probe the universe’s formation and evolution, shedding light on a substance that silently shapes everything around us.
