This is an amazing Hubble image. The yellowish globes are large galaxies forming galaxy cluster RCS2 032727-132623. The stretched out bright blue lines represent a lensed galaxy 5 billion light years behind the "closest" cluster. The "closest cluster" is 5 billion light years away, which means that the light which formed this image left the galaxy cluster before the solar system existed.
