My German Empire

The Prince Oscar launched the "Star No. 1" promotion procedure, the spacecraft started to fly around the earth.

Because Germany has launched several experimental communication satellites, even if the "Star No. 1" fly to the other side of the earth, there will be no problem with communication interruption. Although there are some disturbances, but I can clearly listening to the scene of the exclamation window of Oscar.

After a while, he seems to find a very novelty. "Strange, how can I not see the stars?"

In the middle of the world, the space enthusiasts streams a quite interesting problem, can astronauts see the stars in space?

At first glance, this seems to be a very stupid problem. Most of the stars who can see at night are stars, and the star is the star you can shine, how can I not see? However, this problem was presented once again, not only to the moon, but also the moon, but also, including the ordinary public, it seems to know somewhere. I can't see the stars in the space.

The origin of this misunderstanding is usually traced back to an interview with Apollo No. 11 astronauts, alleged Nille Armstrians that he can't see the stars in space.

But the actual situation is that several astronauts are discussing at the day on the day of the moon. They can't see the stars. As for why the sky can't see the stars during the day, the sky is black, that is because there is no atmosphere in the moon, there is no scattering effect when the sun shines, so the sky is dark; there is also a bright, of course, Will you have the star, so you can't see the stars.

There are some photos taken in space, the background is black, and I can't see any stars. This is because when photos such as planets or satellites are filmed, there will be no longer long time exposure to clearly see those dull starlights. In any photo, if you want to capture your stars, the most important thing is to expose settings. For example, dark nights, you can see thousands of stars outdoors (on earth), but if you just pick up your camera or mobile phone quickly capture, then you will only be dark.

Therefore, in space wants to shoot stars, you need to use delay photography, the shutter is going to open for a few minutes or even hours, so enough photon hits the film to get the image of the stars.

Janik picked up the microphone and explained. "That's because the sun is straight into the spaceship, covering those stars, of course, I can't see it. When the spacecraft enters the globes, you can see the stars."

At this time, Dr. Obert reminded. "Under the Oscar, you will see the sunset on space."

"Oh? Then I have to appreciate it." After five minutes, there is a bit no sign in Oscar. "Oh, this is too fast, the sun will go so!"

The sky is alternate and the earth in space, the sky is alternating on the earth is a slow process, while the night is alternately with the radius to describe it. Because the spacecraft flying is extremely fast, when the spacecraft flies into the Yangfang from the mid-face, the sun suddenly came out, when the spacecraft flew from the yu, the sun was like "whirlwind". If the spaceship flew around the earth in a 90-minute speed, the astronaut on the spaceship can see 16 daily sunrise within 24 hours.

However, his attention is then attracted to the scenery outside the window, and it is self-exclaimed. "So many stars, it's a star sea!" Because there is no air in the space, there is no airfringence and refraction, astronauts see more, brighter than the earth, and there is no flashing; this situation can only Use it to be spectacular.

Yatik took the way. "So our journey is the star sea, one day, one day, we will leave the cradle of the earth."

The little Elizabeth on the side suddenly asked. "Janick brother, even if you enter the era of universe, people's disputes will not stop?"

"Yeah." Yaki couldn't help but smirk.

Great Theoretical Physicist Steven. Hawkki may lead to threats of human extinction. He believes that there are many possibilities in humanity, and the most disclosed is "artificial intelligence", "human conflict" and "alien civilization".

The sci-covered science fictions in the later world have described various "artificial intelligence" and "alien civilization". Most of them "artificial intelligence" and "alien civilization" are hostile to humans, and they will never let go. Hawking believes that even if "artificial intelligence" and "alien civilization" have not destroyed humanity, human civilization may be extracted, ending in the conflict between themselves. Human selfishness, greed, and no-conditioned expansion, the advancement of science and technology has created a weapon that can destroy humanity. "The risk of life on earth is increasing, such as sudden global nuclear war, genetic engineering virus or other dangers we have not imagined." Among them, the global nuclear war is formed between human civilization. A horrible and strange deterrence is most worrying.

In the face of such threats, Hawko believes that space exploration and space immigration are the ideal solution. After all, the earth's resources are limited, and the human living space and resource extension is indeed the only way to continue human civilization.

At this time, the voice of the prince Oscar sounded again. "This is coming to the continental continent." A small sunshine in the morning shot on the North American continent, let him clearly see the contour of this continent. "Do you want to say a greet with these Americans?" The communication between "Star No. 1" and the launch base is an encrypted frequency band, even if it is captured by other radio equipment, it is not a regular noise, but he is still You can say yourself with the bright communication.

Jenik laughed. "Still calcul, so excused those poor guys." So far they have launched several satellites, Yaki thinks that Americans should have discovered that there are more things in the sky, but also guessed is the means of Germany. However, these Americans are afraid to dream, they will not think that their own lives can be sent to space, and they fly a few hundred kilometers in their head.
