The offhand curiosity that most people feel for matters scientific focuses powerfully for some into a life's pursuit, or perhaps compulsion.
Chet Raymo and Norman Davidson have written highly personal books which are individual expressions of each author's love of astronomy.
Davidson is concerned that the results of modern astronomy will be unintelligible to the public because so much of what is done in present research uses concepts of the sky that are abstractions of what is seen. It is his avowed purpose to provide an exposition of the relationships between astronomical concepts of solar systems phenomena and what is actually seen. The development of modern concepts has taken a long time, and Davidson ranges widely for his sources, drawing from Ptolemy and Einstein, from Palomar and ancient Egypt, from times and places between. His book hitches the Earth to the skies, using history and geometry as the traces. It is a book of logic, not poetry.
Raymo's writing, by contrast, is far from the detached, unemotional objectivity of the stereotypical scientist. His words flow in response to the beauty he sees in the skies, in the results of research on these phenomena, and in the connections of these with facets of life around him. For Raymo, it is the synthesis of perception and conception that is important. When he describes the Milky Way, the concepts culminating all the galactic structure research of the century are sprinkled on six pages (with implied concern that the reader not be hindered by the myriad steps which led to those results). Both the phenomena and their explanations have beauty for the mind's eye, for which Raymo also pens his personal, often lyrical responses.
