SHORTEST NIGHT, LONGEST TWILIGHT

June brings long twilights to the Northern Hemisphere. In much of Canada and Europe the Sun's glow is visible all night along the northern horizon. Twilight is of. cially divided into three stages. During civil twilight, you can read a book outside. By the end of nautical twilight, many stars are visible. During astronomical twilight, most people think that it's fully dark, but stargazers complain that the Milky Way looks washed out.
