I almost touched the moon

Cheng Che looked at the caller ID on his phone in disbelief. He hadn't even dried himself after taking a shower. He just wrapped himself in a bath towel and picked up the phone. The joy in his voice almost overflowed from the screen.

"Sister, why did you call me suddenly?"

"Didn't you say that I never call you first? I got off work today and had nothing to do, so I called you."

Cheng Che heard the breathing sound coming from the other end of the phone, frowned and said, "Are you smoking again?"

"How do you know?" Wen Song said jokingly, "Did you install a surveillance camera on me?"

"I do want to." Cheng Che laughed dryly at himself.

"Don't even think about it." Wen Song lowered his voice with some displeasure.

"Sister, I was just joking." Cheng Che quickly begged for mercy, "Please don't be angry, please. You should smoke less, it's not good for your health."

"I know. You're so nagging." Although it was a reproach, there was a hint of pouting in her tone. "Have you finished your training?"

"Yeah." Cheng Che said with a smile, "I just finished taking a shower."

Wen Song said "yeah", but didn't know what to say. Thinking of Xia Ninghe's words, he asked, "What are you having for dinner?"

"Garlic beef short ribs and vegetable salad. I made them myself. Where's your sister?"

"Thuringian sausages and baked potatoes."

"Not bad." Cheng Che nodded and said with a smile, "Finally it's not a lye bun or a bagel. Baby, what are you busy with recently?"

"I told you not to call me baby!" Wen Song frowned.

"Okay, so what are you busy with recently?" Cheng Che asked with a smile.

"Not even BB." Wen Song snorted coldly, "Don't be disrespectful."

"Why are you the same as Koreans and Japanese, being so particular about age and hierarchy?" Cheng Che smiled and said, "Baby, aren't you Swiss?"

"I just think it's very strange." Wen Song laughed awkwardly twice, "Okay, call me whatever you want."

"Okay, I won't tease you anymore. What are you busy with recently?" Cheng Che asked again.

“It’s still my practical project. The main topic is the physical and chemical properties of KBOs.”

"What?" Cheng Che didn't react to what she said for a moment, and asked again, "KBO? What is it?"

"It's the abbreviation of Kuiper Belt Objects." Wen Song explained, "In Chinese, it should be the physical and chemical properties of Kuiper Belt Objects, because ESO happens to have a project to deeply understand the formation and evolution of the outer solar system."

"It's the celestial body where Pluto is located." Cheng Che finally understood her research direction. "It's my sister's favorite planet. That's great."

"It's all the same, actually. I don't have any special feelings for these celestial bodies. But luckily I applied for this project, otherwise I would have to study Jupiter's Great Red Spot or look for possible life on Jupiter's four Galilean satellites."

Wen Song chuckled and said to him, "I don't want to do that kind of research. Extraterrestrial life has nothing to do with me. If it really exists, can it destroy the earth?"

"Song Song." Cheng Che frowned, "You are talking nonsense again. If the earth is destroyed, we can't be together."

“Who knows.” Wen Song half-jokingly said, “Maybe we will pass through the event horizon, fall into a black hole and enter the singularity. In that case, time and space will be distorted, and people may gain eternal life.”

"Really?" Cheng Che asked.

"It's fake, I'm kidding you." Wen Song smiled, "No, it can't be said to be fake. After all, no one has been to the singularity, so no one really knows what will happen."

"Oh, right." Wen Song suddenly thought of something and sent a photo to Cheng Che.

"Does it look good?" she asked.

"It looks good." Cheng Che looked at the photo and felt happy. This was the first time she took the initiative to share her life. "A photo of Jupiter?"

"Yes." Wen Song said, "The observatory in the Atacama Desert in Chile just sent over an image of Jupiter today. Look carefully at the poles."

"The poles?" Cheng Che followed her words and looked carefully. Sure enough, he saw large areas of shining blue light at the poles of Jupiter.

"So beautiful, is that the aurora of Jupiter?" He remembered that Wen Song once told him that the aurora of Jupiter was the most gorgeous in the entire solar system and he would take a picture of it for him.

"Yes." Wen Song said, "I chose this photo from a bunch of photos. This one is the best and the aurora is the clearest."

"So romantic." Cheng Che said emotionally, "Baby, why are you so romantic all of a sudden?"

"Really?" Wen Song asked back, "Do you really think it's romantic?"

"Yes." Cheng Che said, "I think it's more beautiful and spectacular than the aurora we saw in Finland."

"But Jupiter's aurora is scary." Wen Song laughed twice and explained, "Jupiter's aurora is different from Earth's aurora. Earth's aurora changes with the strength of the solar wind, but Jupiter, due to its own strong magnetic field, Jupiter's aurora is permanent and much stronger than Earth's aurora, and it also releases more energy."

At this point, Wen Song smiled even more. "The energy released by Jupiter's aurora will heat the polar regions to over 700 degrees Celsius. So, it's not romantic at all, but very horrible."

"Well, it turns out that this is the Iseylia I know. She has nothing to do with romance." Cheng Che smiled helplessly.

"How are you?" Wen Song asked, "Have you had good training results recently? Are you still obsessed with double cork1800?"

"I haven't been fighting hard recently." Cheng Che said, "I have considered your opinion for a long time, and it has changed. Cork1800 is indeed too extreme and too dangerous. I'd better make sure I can win a medal in this World Cup. I have also been practicing ski cross recently. Speed ​​​​competition is not my strong point, so it feels a bit difficult."

"It's okay." Wen Song comforted him, "No one can do everything perfectly, just like me, I can't do multiple things at the same time. Slopestyle is already your strong point, just treat ski cross as a simple hobby, as long as you participate, there will be no regrets. As for the medal, it doesn't matter, right?"

"Yeah, you're right." Cheng Che looked at the time and it was already past midnight. "Are you sleepy? Do you want to go to bed first?"

"A little bit." Wen Song yawned, "I'm already lying down, how about you?"

"I'm lying down too." Cheng Che stretched and said, "Alas, I have to get up early for training tomorrow. I'm so tired."

"I have to go to work tomorrow too." Wen Song said with a sad face, "But going to work is better than going to school. At least I don't have to stay up late. And we can be the first to see the latest photos of the universe. Some of the photos are really spectacular."

"I want to see them, too." Cheng Che said, "Songsong, let's go stargazing sometime, okay? I don't think I've seen the stars since I was ten years old."

"Okay." Wen Song was a little sleepy, his voice getting lower and lower, and he said lazily, "Let's go to Chile during Christmas. The Atacama Desert in Chile is the best place in the world to observe the stars."

"Okay." Cheng Che's voice was also a little low, "Let's go together."

"Song Song." He asked again, "Your birthday is in more than ten days. What birthday gift do you want?"

“Really?” Wen Song yawned again. “I forgot about that. As for birthday presents, I hope my paper can be included in the Annual Review of Earth and Planetary Sciences or the Journal of Cosmology and Astroparticle Physics.”

"Then I probably can't help you." Cheng Che smiled and said, "But I believe you can do it. What other gifts do you want? Or, how do you want to spend your holiday?"

"I don't know." Wen Song's voice was very soft, "I don't like celebrating my birthday. Che... I'm sleepy, good night."

"Good night, sister." Cheng Che's voice was very soft, and it seemed even more gentle and magnetic. "Can you please not hang up?"

"Okay..." Wen Song said softly, put his phone aside, and soon fell asleep.

Cheng Che listened to the breathing sound coming from the phone, smiled slightly, and fell asleep unknowingly. In his dream, he seemed to have arrived in the Atacama Desert in Chile, standing under the gorgeous Milky Way with Wen Song. It was a beautiful scene, and it couldn't be just a dream.
