MACS J0416.1-2403or MACS0416 abbreviated, is acluster of galaxiesat aredshiftof z=0.397 with a mass 160 trillion times themass of the Suninside 200kpc(650kly). Its mass extends out to a radius of 950 kpc (3,100 kly) and was measured as 1.15 × 1015solar masses.[2]The system was discovered[3]in images taken by theHubble Space Telescopeduring theMassive Cluster Survey,MACS.[4]This cluster causesgravitational lensingof distant galaxies producing multiple images.[5][6]Based on the distribution of the multiple image copies, scientists have been able to deduce and map the distribution ofdark matter.[7][8]The images, released in 2014,[9]were used in theCluster Lensing And Supernova survey with Hubble (CLASH)to help scientists peer back in time at the early Universe and to discover the distribution of dark matter.[10]
