«Die rote Grenze» is Timothy Ferris's popular science essay, published by Springer in paperback (205 pages, in German).
The book recounts how it was discovered that the universe is expanding: the light from distant galaxies shifts toward the red, a sign that they are moving away from us. It also explains the role of quasars discovered in 1960 and of the redshift in the idea of an observable limit of the cosmos, as well as the work of the astronomers who investigated that frontier.
This work, published in 1982, bears the subtitle «Auf der Suche nach dem Rand des Universums» and includes an introduction by Carl Sagan.
For readers interested in astronomy, cosmology, and the history of science.
