This image compiles different times in the history of the universe: present day, 4 billion years ago and 11 billion years ago. The side-by-side comparison shows astonishing differences between the galaxies. The image of the universe today shows big, fully formed and elaborate galaxy shapes. Going back in time, the galaxies become smaller and less mature, as they're in the process of forming. The galaxies at earlier times are split between blue star-forming galaxies with a more intricate structure -- such as discs and bulges -- and colossal red galaxies that are no longer forming stars.

Those who knock government workers ought to be reminded that a lot of the credit for the ability to capture these kinds of images/ideas goes to scientists and engineers who guess what, are government employees.

And to think we were going to allow it to die a few years back and drop into the ocean. I am so glad that did not happen.
