MACS J0416.1-2403 is a cluster of galaxies 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] Based on the distribution of the multiple image copies, scientists have been able to deduce and map the distribution of dark matter.[7][8]

  • MACS J0416.1-2403 contains a significant amount of dark matter, which leaves a detectable imprint in visible light by distorting the images of background galaxies.[9]

  • Very massive cluster of galaxies, MACS0416.1-2403, located roughly 4 billion light-years away.[10]

  • Galaxy cluster MACS J0416.1–2403 is one of six being studied by the Hubble Frontier Fields programme.[11]
