Top 10 Images of Hubble Space Telescope

This is NASA/ESA Hubblecast 57: Top 10 Images – Hubble’s Hidden Treasures Unveiled.
Producing the stunning pictures that Hubble is famous for isn’t straightforward. Unlike your typical digital camera, which automatically sets things like contrast, exposures, colour balance and so on, Hubble is not optimised to produce aesthetically pleasing pictures. It’s optimised for science. Turning these scientific images into amazing images of the cosmos is not easy, as all of these variables have to be tweaked by hand. That’s called image processing — and it is a mixture of science and aesthetics.
