The book Outside the Solar System begins by discussing the history of space exploration. Then the book takes the reader on an imaginary journey from Earth into the distant reaches of the Universe beyond our Solar System. Along the way, the reader encounters and learns about a variety of deep-space features, including stars at different life cycle stages, exoplanets, nebulas, supernovas, black holes, and galaxies.
