You probably think that astronomy is a complex and boring science. But no! Have you ever wondered why a spherical moon in the night sky sometimes looks like a luminous circle, and sometimes like a sickle? And if the constellation Ursa Major has more than 100 stars, then why is it portrayed as a bucket figure consisting of only seven? Do UFOs really exist, or are they just human fantasies? Are there seasons on other planets? How are astronomy and calendar related? What is the Milky Way? Where does the comet's tail come from?
