MACS J0416.1-2403 is a galaxy cluster at a redshift of z=0.397 with a mass 160 trillion times the mass of the Sun inside 200 kpc (650 kly). Its mass out to a radius of 950 kpc (3,100 kly) was measured as 1.15 × 1015 solar masses.[2] The system was discovered[3] during the Massive Cluster Survey, MACS.[4] This cluster causes gravitational lensing of distant galaxies producing multiple images.[5][6] In 2015, the galaxy cluster was announced as gravitationally lensing the most distant galaxy (z = 12).[citation needed]
