Not a bad view, for 4 billion years ago.

Very far out, indeed. 

The image above shows the galaxy cluster Abell S1063, which is “potentially home to billions of strange new worlds” according to scientists working with the Hubble Space Telescope.

Visible near the center of the image, the cluster appears as it was four billion years ago

The photograph, released on Thursday, was NASA’s astronomy picture of the day Friday.

While the Hubble Telescope is extremely powerful in its own right, this view is made even more impressive by a natural phenomenon called gravitation lensing. 

“The huge mass of the cluster distorts and magnifies the light from galaxies that lie behind it,” according to the team at Hubble. This altered spacetime “allows Hubble to see galaxies that would otherwise be too faint to observe and makes it possible to search for, and study, the very first generation of galaxies in the Universe.”

These conditions allow the observation of galaxies much older than Abell S1063. For instance, one of the galaxies behind it is approximately 12.7 billion years old, according to
