  • An attempt has been made in these pages to trace the evolution of intellectual thought in the progress of astronomical discovery, and, by recognising the different points of view of the different ages, to give due credit even to the ancients. No one can expect, in a history of astronomy of limited size, to find a treatise on “practical” or on “theoretical astronomy,” nor a complete “descriptive astronomy,” and still less a book on “speculative astronomy.

  • Astronomy is a difficult science and it is a challenge to understand even the stars that compose the brightest system on the night sky: Sirius (α Canis Majoris=α CMa). This is one of the nearest stars and the brightest one as seen from Earth, with the exception of our Sun. At present, perhaps unfortunately, stellar astronomy and in particular the study of the very bright stars are not part of the mainstream astronomy research. The professional attention is now focused on the cutting-edge of cosmology, the early Universe, extremely distant galaxies, the “origins” theme, etc.
