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.

Introduction to Astrophysics – Yale

This is a series of lectures about Astrophysics from Yale University. Taught by Professor Charles Bailyn,these lectures are aimed towards non-scientists. So it’s great in explaining some difficult concepts. What is even more interesting, this course focuses on three particularly interesting areas of astronomy that are advancing very rapidly: Extra-Solar Planets, Black Holes, and Dark Energy. Particular attention is paid to current projects that promise to improve our understanding significantly over the next few years.
