Hubble Frontier Fields fulldome view of MACSJ0717.5+3745

This fulldome video shows the galaxy cluster MACSJ0717.5 3745, which was observed by the ESA/Hubble Space Telescope as part of the Frontier Fields programme. Using the effect of gravitational lensing caused by the mass of the cluster, this programme allows astronomers to study some of the earliest galaxies in the Universe.
