Across The Universe, Cont. - Zoom In On Galaxy Cluster Abell 370

Fascinating (watch full screen!):

From NASA/ ESA, May 4, 2017: This zoom starts with a ground-based view of the sky and zooms in on the distant galaxy cluster Abell 370, as seen by the NASA/ESA Hubble Space Telescope.

The mass of the cluster is large enough to bend the light of more distant objects along the line of sight. This creates interesting distortions, fascinating arcs and it even magnifies objects which would otherwise be to faint and tiny to be seen by Hubble.
