1,140 Canon 400mm f/2.8 Lenses Will Search Space for Dark Matter

Summary

The MOTHRA telescope, under construction in Chile, is the world's largest all-lens array, utilizing 1,140 Canon EF 400mm f/2.8L IS telephoto lenses. These lenses are arranged in groups across 30 mounts and will be used to detect faint light, specifically diffuse ionized gas between galaxies. Researchers selected these Canon lenses for their optical performance and chose the EF mount for accessory compatibility. The project aims to capture the first image of the cosmic web, which is thought to be composed of dark matter.
