Among the many galaxies, the galaxy is a relatively large galaxy. Some small galaxies have only hundreds of stars, while the Milky Way includes 100 billion planets, and our sun is one of them.

The sun is a medium-quality star. It was formed 4.5 billion years ago and is expected to have a life span of about 5.5 billion years. When we look at the stars, we will also find that some stars should be brighter and some are darker.

In addition to the distance and size, this is also affected by the age of the star. Young stars are lighter, and older stars are darker.

The size of the entire galaxy is very amazing. It has a diameter of about 100,000 light years. In other words, it will take 100,000 years from the end of the galaxy to reach the other end. The thickness of the Milky Way is uneven.

The center of the Galaxy is about 20,000 light years, and the thickness of the edge part is about 1,000 light years.

The starry sky in the southern hemisphere is often more attractive than the northern hemisphere because the brightest central area of the Galaxy will rise there.

Gallwell Forest Park

The Gallwell Forest Park in Scotland is one of the four major night parks in the world, and it is also a British golden-grade dark starry area. During the day, the park has dense forests.

At night, there are countless stars here, which is beautiful and quiet. In 2009, the park was awarded the honorary title of "Dark Night Park" by the International Dark Night Association and was designated as one of the best places to watch stars in the world.
