Quite interesting as it contains a lot of sky maps organized on days and hours. Every month there's information on where planets of the solar system are positioned along with the Moon and several bigger stars. You might find information such the position of the Sun on the 21th of June in the Northern Hemisphere, the 13th sign (Ophiuchus), which can be seen in June, in the southern hemisphere and important dates of great astronomers. There's also information on former space missions, such as Apollo 11 and some of its on board experiments. The 1910 Halley's comet orbit is described and the social implications of the created panic. It's a nice book, worth having.
