In Japan, the Harvest Moon is called “Chūshū no Meigetsu,” or the “Mid-Autumn Moon.” It’s the most beautiful full moon of the year, typically seen in September.

Observing the sun is both important and fascinating. It’s essential to use special filters or telescopes and never look at it directly. The best times for solar observation are on clear days in the spring or autumn when the air is crisp. You can see interesting features like sunspots and prominences during these periods.

The Andromeda Galaxy is easy to observe in the Northern Hemisphere during the fall and winter months, with October and November being especially ideal. New moon nights, when there’s little moonlight, provide the best viewing opportunities. Located to the northeast of the constellation Pegasus, it can sometimes be seen with the naked eye, but binoculars or a small telescope offer a much clearer view.

Also called a shooting star

Meteors can be observed with the naked eye, but they are especially numerous during meteor showers.

They emit light as they enter the atmosphere and are visible as streaks of light. They are very small, usually a few millimeters to a few centimeters in size.

A telescope with medium magnification is suitable for observing craters and mountain ranges on the Moon.
The same side always faces the earth due to the phenomenon of synchronous rotation.
