Its contribution includes the information survey of Jupiter and Saturn, and provides a lot of exquisite photos for mankind. Among the many photos, one of the most prominent is the last photo taken by Voyager 1 after it left the solar system. The content of this photo is quite simple. A dot appears in the dark blue picture, which is very eye-catching. What does it represent?

From the picture, it is a small blue dot. In fact, it is the real appearance of the earth. In this picture, the earth is only pixel size. In the eyes of human beings, the earth is boundless and a huge planet. According to the calculation, 150 million square kilometers of land can survive 120 billion people, which shows that the earth is much more powerful than we think. In the solar system, the volume of the sun is 130 times more than that of the earth. That is to say, one sun can hold 130 earths. There are many stars of the same size as the earth in the universe, which are more vast than the earth.

I can’t believe what the earth looks like

Seeing the insignificance of the earth, many people can’t help sighing that human beings are so weak that it’s not worth mentioning. When they saw this little blue dot, many people couldn’t believe that it’s the earth we live on at the beginning. Some even questioned that the dim blue dot photographed by travelers is not the earth. After all, there are so many lives on the earth. According to the truth, it must be huge Big, never so small.

But in fact, the authenticity of this picture is reliable. The earth is very small in the universe, just like a grain of dust. I want to really find out how big the universe is. It may not be possible in the limited human life. Mankind has always had a great dream, that is to find out the area of the universe, how big is it? Human beings have always set this goal in the front, and only by inspiring themselves, can they have greater motivation. In the process of exploration, there is a long way to go.
