This book takes the reader on an exploration of the structure and evolution of our universe. The basis for our knowledge is the Big Bang theory of the expanding universe. This book then tells the story of our search for the first stars and galaxies using current and planned telescopes.
Various kinds of masks obscure our view of our galaxy, the Milky Way, as well as of other galaxies. Masks of interstellar dust affect our measurements within galaxies, on scales ranging from individual supernovae to the galaxies themselves. The “mass mask” (our inability to image mass rather than light) gives astronomers a very incomplete picture of the size and structure of galaxies themselves, because we cannot image the dark matter which provides most of the galactic mass. Another mass is the “dynamical mask” ng.
Astronomy: Stars, Galaxies, and the Universe (Audiobook, mp3)
Even to the unaided eye, the sky displays a richness of sights. Stars of different brightnesses and colors spangle the blackness of night. Here and there are pairs and clusters. If the right time of year, a band of white encircles the heavens, the Milky Way, bejewelled with bright stars and stamped with mysterious voids. Binoculars and small telescopes reveal more: the Milky Way is made of countless faint stars, while double stars, clusters, and clouds of swirling gas abound.
