A light-bending cluster of galaxies 9 billion light-years away is NASA’s Friday photographic gift to people who want to end the work week with deep thoughts.

Or just see something amazing.

The photo by the Hubble Space Telescope focuses on galaxy cluster eMACS J1823.1+7822. It’s one of five “exceptionally massive galaxy clusters” Hubble recently explored, NASA said.

“Like a submerged sea monster causing waves on the surface,” NASA said, “this cosmic leviathan can be identified by the distortions in spacetime around it.” Spacetime is the mathematical model that combines the three dimensions of space with time into a single expanding thing.

“The contorted streaks and arcs of light we see in this image are the result,” NASA said. And there’s more. A “host of galaxies” surrounds the cluster.

The image itself uses data from eight different filters and two cameras on Hubble. “The combination of observations at different wavelengths lets astronomers develop a more complete picture of the structure, composition, and behavior of an object than visible light alone would reveal,” NASA said.

NASA’s Marshall Space Flight Center in Huntsville, Ala., was the lead NASA field center for the design, development, and construction of the Hubble Space Telescope.
