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