Serpent) there is a new star in the formation of the circle, its peripheral blue misty ice circle, 175 light years from the earth.
Astronomy generally believes that comets in the solar system carries a large amount of water molecules, providing water resources for the formation of oceans on the earth. This observation further proves this fact. It is no accident that curiosity finds water marks on the surface of Mars. The problem is where the water on Mars is now.
In the distant past of the Universe, water molecules (H2O) are very common components. Today, with the progress of human civilization, the generalization of abstract concepts has been completed. Curiosity has carried the human mission to Mars for exploration and found many "secrets" of Mars ", greatly broaden the horizons of mankind. Humans must take good care of themselves and take good care of the scientific and technological civilization they have created. Basic mathematics is a shining "Pearl" in the field of science and technology. We need to be careful.
