If someone asks which is the closest star to the Sun? I believe that if you are a lover of astronomy, you can immediately give the answer, and if not surprisingly, you can even say that the distance between this star and the Sun is about 4.22 light years, but if you ask which is the second closest star to the Sun? That's not easy to answer.

Artificial Moon
When it comes to the moon, all of us can think of the wonderful dream of Change running to the moon and the rigorous hardship of Wu Gang fetching laurels, and when we think deeper, we can think of man landing on the moon and technological progress. However, it is also because of the continuous progress of technology that we humans have a bold idea - "artificial moon".

"State of Chaos"
Past studies have shown that past shifts in Earth's climate patterns have usually been driven by external factors, such as super volcanic eruptions, impacts of small bodies, solar activity, or changes in the Earth's orbit. This has never happened on Earth in the past.

How light reaches the speed of light
Light is everywhere in our lives. It is the most common thing we see in life, but also the most mysterious thing around us. In the vastness of the universe, light travels at great speed between the stars, bringing light sources to the planets.

If evolution is correct
The modern evolutionary theory believes that all existing organisms on the earth are those primitive beings that evolved over a long period, and in the process of evolution, due to the existence of genetic mutations, organisms will undergo some subtle changes from time to time in the process of reproduction from generation to generation. If some changes are conducive to better survival and reproduction, then these changes will pass the test of "natural selection" and be preserved and passed on from generation to generation, while the other way around, they will be eliminated by "natural selection".

View of the Earth from the Moon
Facing the stars in the universe, human beings have always wished to leave their own "interstellar footsteps" in it. There are so many mysteries in the vault of the universe that we do not know. Late at night, we always look at the bright moon hanging in the sky and imagine the stories that happen at the upper end of the moon.
