Strong gravitational lenses occur when massive galaxy clusters warp and distort the light from background objects. These lenses frequently show up im images as arcs and streaks.  

In this edition of Live From NOIRLab@Arizona, Xiaosheng Huang will share the fascinating story of how the DESI Legacy Imaging Surveys have almost doubled the number of known strong graviational lenses.
