Scientists have created the most detailed map of dark matter using NASA’s James Webb Space Telescope. Dark matter, which makes up most of the universe's matter, cannot be seen directly but its gravity bends light from distant galaxies, allowing astronomers to identify its presence. The new map, produced by a team at Durham University, reveals that dark matter is not randomly scattered but is connected to visible structures. This area of space lies in the constellation Sextans and has been mapped in unprecedented detail, identifying around a million galaxies, which is double the previous record from the Hubble telescope. The map is expected to aid future space missions.
