How to see the Milky Way
Since the Milky Way is faint, it is difficult to see if it is affected by moonlight or light pollution caused by artificial light. In Japan, the number of places where you can see the Milky Way has decreased since the 1970s. 70% of the Japanese cannot see the Milky Way because of light pollution.
To see the Milky Way, go to a place as high as possible away from the city on a sunny night without moonlight.
The Milky Way can be seen all year round, but because the Milky Way is located in Sagittarius in the direction of the center of the galaxy, the Milky Way in the direction of Sagittarius is relatively bright and easy to see. The Milky Way in the opposite direction is faint and difficult to confirm. In the Northern Hemisphere, Sagittarius is a constellation of summer, with the Milky Way in summer appearing thick and the Milky Way in winter appearing light.
