Let us unravel the mystery of the starry sky with everyone's "I saw it"!

How do we see the starry sky? We usually look up at starry sky casually, but when we think about it, we will realize that there are mysteries. "Why can't we see the stars (first-magnitude stars) in the daytime?" "Why can we see the Milky Way in the dark?" Have you ever wondered about those mysteries? The reasons are not clear (not investigated), although there are individual differences in how stars look. In this project, we will challenge the mysteries related to starry sky observation by observing the "extra-close" encounter of Jupiter and Saturn that will occur in December 2020 by many people around the world.
