The starry sky is one of the most awe-inspiring landscapes in nature. As night falls, the stars of the universe twinkle overhead, creating a spectacle of countless diamonds that embellish the dark sky.

Under the starry sky, people can feel the vastness of space, the infinite possibilities, and the profound mysteries of the universe. In this article, we will introduce some fascinating facts about the starry sky.

The solar system is the center of the universe, consisting of all the celestial bodies that are bound by the sun's gravitational force. This includes eight planets, at least 165 known satellites, five identified dwarf planets, and hundreds of millions of small solar system bodies.

A star cluster is a celestial system made up of a dozen to millions of stars that share a common origin and have a strong mechanical connection between them.

The Milky Way is a massive star system containing over 200 billion stars, with the sun being an ordinary member of this system. Nearly all the stars we see in the sky are part of the Milky Way.

Due to the earth's atmosphere, interstellar matter, and human vision limitations, we can see only a fraction of the stars in the Milky Way, around 6,000 stars throughout the year.

Stars are hot, gaseous, spherical, or spheroidal celestial bodies that emit light and generate heat by themselves. The lifespan of a star depends on its rate of production and energy consumption.

A star with a higher mass has a shorter lifespan, while one with a lower mass has a longer lifespan. Most stars are between one and ten billion years old.

The universe is a vast and mysterious world full of unknowns and exploration possibilities. Our understanding of the universe is still limited, and many cosmological questions remain unanswered, such as the nature of dark matter and dark energy.

The existence of these problems makes the universe more enigmatic, arousing people's curiosity. The mystery of the starry sky is also reflected in our understanding and perception of it.

In modern times, we use astronomical telescopes to study the starry sky and explore the mysteries of the universe by examining celestial objects and phenomena. All of this shows that the starry sky holds a vital position in people's hearts.

Both planets and stars have unique colors. The color of planets may depend on the concentration of the atmosphere.

For example, Mars and Mercury, which have thin atmospheres, show their natural colors. In contrast, Venus, Jupiter, Saturn, Uranus, and Neptune, which have relatively thick atmospheres, exhibit vivid colors based on the composition of their atmospheres and the effects of reflection and absorption.

The starry sky is one of the most beautiful, mysterious, and significant landscapes in nature. Under the starry sky, people can feel the vastness of the universe, the infinite possibilities, and the profound mysteries that await discovery.

The starry sky is not only a symbol of culture and spirit but also an essential reference for humanity's exploration of the universe and realization of long-distance voyages. Therefore, let us cherish and protect the starry sky, and appreciate the beauty and mystery it holds.
