In space, these rings and associated shapes appear when light from distant sources is bent by a massive galaxy or group thereof. Our lens bends light exactly the same way a black hole weighting 75% of Earth mass would. This experiment, and the background about this phenomena are described in details in the paper didactical experiment on gravitational lensing
