Hyper Suprime-Cam Image of a Location with a Highly Significant Dark Matter Halo

Caption

Hyper Suprime-Cam image of a location with a highly significant dark matter halo detected through the weak gravitational lensing technique. This halo is so massive that some of the background (blue) galaxies are stretched tangentially around the center of the halo. This is called strong lensing.
