When Qiao Bao woke up, it was already night, and he found that the door of the small room was ajar, and his parents didn't know where he had gone.

"Dad? Mom? ”

Qiao Bao rubbed his eyes, got up with a mutter, looked for the light, and came to the kitchen, "Wow, it smells so good!" ”

Qiao Bao saw that there was his favorite sweet and sour pork ribs on the table, and hurriedly climbed into the chair and ate it in a big gulp.

"How's it going, is it delicious?"

Qiao's mother leaned over and smiled at Qiao Bao, "Come here when you're full!" Mom and Dad have a reward for you! ”

"Reward!"

Qiao Bao jumped up happily and hurriedly ran to Qiao's mother, Qiao's mother picked him up and came to the balcony, only to see Qiao's father adjusting the binoculars, not knowing what he was looking at.

"Dad, what are you looking for?"

Qiao Bao ran to Qiao's father curiously, "Qiao Bao wants to see it too!" Daddy let me see it! ”

"Wait a minute, Qiaobao, Daddy is looking for Mars."

Qiao's father determined the location of Mars, and gave the telescope to Qiao Bao, "Qiao Bao, come, look at it, this is Mars, the weather is good today, you can see it very clearly!" ”

"Really!"

Qiao Bao looked into the camera and saw an orange planet, among the colorful stars, but it was not so bright.

"Wow! This is Mars! ”

Qiao Bao exclaimed, "It's a pity, Pink Moon is not here, otherwise he can introduce me to the knowledge of Mars." ”

"There's no Pink Moon, and Dad!"

Father Qiao raised his head proudly and said to Qiao Bao: "Mars is also a terrestrial planet, a desert planet, and the main planet of Aries. ”

"Eh, Dad, why does Mars look different? It's a little darker on one side, and it's a little brighter on the other. ”

Qiao Bao observed Mars for a while and asked curiously.

"That's because, to the south of Mars, there are ancient highlands full of craters, and to the north are young plains, so it looks completely different."

"And, on Mars, we've found liquid water, and saltwater lakes! ”

"There is water! Isn't that life!? ”

Qiao Bao was even more pleasantly surprised, "The universe is so big, there are so many planets, there must be more life than just the earth!" ”

"This, I don't know, the salt water lake of Mars also once existed, and whether there is life now still needs to be studied by scientists."

Daddy Qiao touched his chin, "Moreover, the temperature difference between perihelion and aphelion of Mars is close to 160 degrees, and in this regard, it is not suitable for the survival of creatures on Earth." ”

"I see..."

Qiao Bao also followed the example of Qiao's father, touched his chin, pondered for a while, and pushed the telescope to Qiao's father: "Then Dad, the weather is so good today, let's take a look at Uranus, right?" ”

"Okay! Uranus, right..."

Daddy Joe worked hard to adjust the telescope and struggled to find Uranus, "Qiao Bao! Got it! Uranus is too slow to find, it is too far from Earth, and it is a pale dark blue. ”

"Qiao Bao, take a look!"

Qiao Bao looked at the distant planet diligently and suddenly noticed the difference between it and the others.

"Dad, how is Uranus's axis of rotation weird? Different from other planets? ”

"Qiao Bao's eyes are so powerful, you can see the difference at once!"

Dad Qiao patted Qiao Bao's head complimentarily, and said, "Mommy, you can help draw the floor plan, you are very good at drawing." ”

"Okay, no problem, wrap it up on me!"

Qiao's mother took out a blank piece of paper, brushed a few brushes, and drew a picture.
