A Subaru Suprime-Cam image of one of the clusters used in the analysis, A2390, (2.7 billion light years from the Earth). The purple hue shows the dark matter distribution measured by the gravitational lensing effect on distant galaxies (typically 8 billion light years from the Earth), where the darker color indicates the denser dark matter concentration. It shows that the dark matter distribution is elongated along the northwest-southeast direction.
