The astronomical encyclopedia: the universe - space - the Earth

What is the universe and how did it originate, and what are its sections and components? What is the truth about sunspots or what is called (solar blemishes)? These questions may run through all our minds, but we often do not find real explanations for them because that requires reviewing more than one book in astronomy. The astronomical encyclopedia prepared by the author provides all the comprehensive scientific answers about the truth of the universe, space, and Earth, in a simple style that allows non-specialists to obtain unique and strange information. It is presented with illustrative pictures and tables. The author introduces it with an introduction talking about the history of astronomy among ancient peoples, such as the Babylonians, Chaldeans, and Greeks, before taking the reader on a tour through planets, galaxies, and celestial bodies.
