Nasa's Webb Telescope Maps Dark Matter

Scientists have created a new, very detailed map of dark matter using the James Webb Space Telescope.

Dark matter is a mysterious substance that makes up a quarter of the universe and helps hold galaxies together.

Unlike ordinary matter, dark matter doesn't give off light, so scientists have to study it by looking at how its gravity affects the light from distant galaxies.

The new map shows how dark matter has influenced the largest objects in the universe, like galaxy clusters.

This helps scientists understand how dark matter has shaped the universe over time.

Without dark matter, galaxies like our Milky Way might not exist as we know them.

Scientists are now working on a 3D version of the map to learn even more about dark matter.
