Galaxies are peculiar "bricks" in the endless "building" of the Universe. Arising from the dust of the Big Bang, these "bricks" have not been at rest for 13 billion years - they continue to change. James Geech tells the fascinating story of the evolution of the most colourful elements of space: how galaxies came to be; why there are so many of them, they differ in size, brightness and shape; and how they managed to grow black holes in their bowels. As a practicing researcher, Geach lifts the veil of secrecy over the work of an astrophysicist: they fight for funding, write applications for access to telescopes at the last moment before the deadline for the sake of excitement to see what was not yet available to the human eye. And most importantly, Geach explains why the modern astrophysicist is a light hunter, and how you can see the distant past of the Universe.
