The new cosmos offers a coherent introduction to the whole field of astronomy and astrophysics in a manageable size. The corrected and expanded reprint takes into account the rapid progress in astronomical research and observation possibilities in the two years since the first publication of the 7th edition. The most important new results, especially in our planetary system, in the neutrino radiation of the Sun, in the most distant galaxies and quasars, and in the development of the Universe are taken into account.
