The Canada-France-Hawaii Telescope (CFHT) Lensing Survey has released the largest map to date of dark matter. The map is 100 times larger than previous attempts. The team worked for 5 years and imaged 10 million galaxies at distances up to 6 billion light years using the CFHT’s 340 megapixel camera. Then they analyzed the weak gravitational lensing effect to produce a map of the spatial distribution of the dark matter. The results are in line with existing simulations of the evolution of the universe.
