The constellations and the associated myths help to navigate the starry sky and convey the diversity of images from mythology and star legends. Star maps and old copper engravings from the collection of the Austrian National Library illustrate how people envisioned the night sky in earlier centuries. Detailed subject indexes with over 3,000 search terms facilitate access to star and constellation names as well as mythology. The third, expanded edition provides information for the coming decades on where and when planets, star clusters, gas nebulae, and galaxies can be easily found in the sky.
