[Machine Translation] This book is a guidebook of astronomical phenomena, in which a popular museum curator introduces the mechanisms, highlights, and ways to enjoy various astronomical phenomena that occur in the night sky, along with easy-to-understand illustrations. It covers not only major astronomical phenomena such as total lunar eclipses and meteor showers that are covered on the Internet news, but also astronomical events that are a bit geeky but you would like to see at least once, such as 1st magnitude eclipses, disappearance of Saturn's rings, disappearance of Jupiter's equatorial stripes, nova with the naked eye, and more. As you learn more about the astronomical phenomena that occur on each celestial body, you will look forward to looking up at the night sky. Why don't you try astronomical observation with your family tonight?
