Galaxy (two external songs)
Galaxy, a wonderful river.
There are hundreds of millions of bright constellations flowing.
Deep in the universe, rolled up
A mysterious whirlpool with a diameter of 65438+ million light years.
Galaxy, the river of life
The solar system lives in your arms.
Countless lives on earth.
You cultivated the flowers.
People have built a magpie bridge in their imagination.
Let the Cowherd and Weaver Girl enjoy the joy of reunion after a long separation.
solar system
The sun is an unparalleled great mother.
She is 5 billion years old.
She has many children: planets, satellites, asteroids. ...
Formed a big family called the solar system
The children revolved around her happily.
The nourishment of happiness keeps her young forever.
She selflessly dedicated her light and heat.
For thousands of years, it has been endless.
I, an insignificant life.
Willing to be a street warbler who sings for her forever.
mercury
Like a spoiled child
Snuggle up next to Mother Sun.
He whirled lazily.
Walk for 90 days a day and a night.
Sun mother gave him too much love.
Make him willful, eccentric and boring.
During the day, the fever reached more than 400 degrees Celsius.
It is cold to the death line of MINUS 170 degrees at night.
All life cannot exist.
He is the only one who looks at himself and feels sorry for himself.
New exploration of Mars
"Mars Express" came here,
Come to the wonderful house of Mars,
It ran around Mars and shouted:
Hey, Mars, make friends,
I come from distant Europa!
Opportunity and spirit followed.
These two young people from America,
Really want to solve the mystery:
It's time, Martian girl,
You should answer our questions.
The Martian girl is still blushing,
Facing the three boys, he said nothing.
Where does the great mystery of the times begin?
Guess for yourself.
Three strong-willed boys,
Watch carefully day and night.
Some strange sights surprised them.
Antarctica is covered with a lot of frozen water,
Many parts of the surface were washed away by the flood.
There are many hematite pellets embedded in the rock.
Prove that Mars was once a river, full of water!
What magical power made Mars dry up?
Where will possible Martian life settle?
Did you leave some tenacious life?
Are they dormant in the ice, or are they hidden deep?
Underground?
Three boys may not be able to solve these mysteries,
But a group of latecomers will be ready to go.
It is human nature to March into the unknown,
No one can stop exploring the universe!
