God Seven, why didn t I see the stars when I came out of the warehouse?

Stars are actually relatively small planets, stars or whatever, and when you get to that place, they're quite big, so you can't feel the stars.

Interpretation of this paragraph. xīngxīng

Star. Like the stars in the sky. Generally stars.

It's still a little bit and it's small. Pi Rixiu's poem "Sick Peacock": "Today's spring breeze can't blow, and there is a star in the golden wisps of Tianhao." ”

Describe gray sideburns. Zuo Si "White Hair Fu": "The stars have white hair, born in the sideburns. ”

6973 are visible to the naked eye.

There are two main factors that determine whether people observe the stars as light or dark:

One is due to the size of the star's ability to emit light, and the other is the distance between the star and people.

Astronomers usually divide the ability of stars to shine into 25 magnitudes, with the strongest ones being about 10 billion times different from the worst ones.

The brightness of a star is often expressed in terms of magnitude. The brighter the star, the smaller the magnitude. The magnitude measured on Earth is called the apparent magnitude; A magnitude that is attributed to a distance of 10 parsecs from the Earth is called an absolute magnitude.

The magnitude of the same star measured by detection elements that are sensitive to different wavelength bands is generally not equal. One of the most versatile magnitude systems is the U (ultraviolet), B (blue), and V (yellow) trichromatic systems (see Photometric Systems'"class=link> metering system); b and v are close to photographic and visual magnitudes, respectively. The difference between the two is the commonly used color index.

The Sun is of v=equal, the absolute visual magnitude is m=+, the chromatic index is b-v=, u-b=. The color temperature can be determined by the color index.

A star that is close to people has a strong ability to emit light, so people will light up when they see it. However, even if a star is quite capable of emitting light, if it is very far away, then its brightness may not be as bright as that of a star that is tens of thousands of times less capable of emitting light.

Suppose there is a star called Antares that is about 100 million times the size of the Sun and is about 50,000 times more luminous than the Sun, but because it is 410 light-years away from the Earth, one can only see it as a bright star with a red glow. If Antares were to be moved to the position of the sun, the light and heat it emitted would bake the earth into a large stone ball where everything had disappeared.

It was daytime when I left the cabin, and the sun was strong, so of course I couldn't see the stars.

The stars you see in space don't look the same because they don't have the refraction effect of the atmosphere on Earth, so you should have seen it and didn't pay attention.

Stars are what you see on Earth, and in space, you see planets!!

That's a great question!

In fact, astronauts can see the stars in space, but you can't see them on live TV!

This is due to the lack of dynamic range of the TV camera.

In layman's terms, it is the ability of the TV camera to respond to both strong and low light at the same time.

If you brighten the picture so that you can see the stars in the camera frame, then the people and the spaceship you see will be so bright that you can't see anything.

If the picture is dimmed so that the brightness is right for people and the ship, then the stars will be too faint to be seen.

When a person sees in space, he can see both the spacecraft and the stars clearly because of the automatic adjustment ability of the human eye.

This question has been mentioned before, and many people suspected that the US moon landing was a fraud, and one of the reasons was why there were no stars in the moon landing.

The reason is the same: the camera's film doesn't have enough dynamic range to show people and nearby objects clearly and at the same time show the stars.

It seems that there is no air in space. This issue was also questioned in the U.S. moon landing**.

That's because there is a sun, the sunlight is too strong, and the stars shine because the sunlight shines on the galaxies in space and reflects to the earth, and the sunlight obscures the light of the galaxies, so the stars are not visible.

You didn't notice, did you? That's because the sun is shining so you can't see the stars!

Because stars don't shine, they're not easy to find.

In order to allow terrestrial TV viewers to see clearly, the time chosen when leaving the warehouse is when the light is very good, that is, it is equivalent to the day on the earth, and the stars cannot be seen during the day.

The Earth is so bright that if the camera is facing away from the Earth, you should be able to see the stars, after all, it is still difficult to distinguish the stars if you are too close to the bright Earth, just like most stars on the ground are not visible near the bright moon.

There is no light, because there is no air, and the refracted light cannot see far.

There was the sun when I went out of the cabin, and the sun was so strong that I couldn't see the stars. After a while, turn to the back side of the earth, and the earth blocks the sun, and you can see the sky full of stars. The spacecraft orbits the Earth every 90 minutes, 45 minutes during the day and 45 minutes at night.

Angle problems or the camera is too rubbish.

The exit hatch is facing the earth, and the camera can't shoot that far. Lighting issues.

The earth is too reflective.

Switching to the dark side may be visible.

It may also be that the camera equipment is not good.

It's only through the atmosphere that you can see the stars because of the optical principle.

Because it was daytime, the sunlight blocked out the starlight.

I don't know, big brother or big sister, you go to the encyclopedia to find it.

Because the universe has no atmosphere, the scattering of starlight is not enough, and ordinary cameras cannot photograph stars.

Stars are actually caused by reflections from other planets. It could be an angle issue.

Because of the difference in the rate.

Obscured by the rays of the sun,

From the stars, love the earth.

I am from the stars and you are from the earth.

A professor from the stars.

Why do I think this recommended answer is a bit unanswered, this can also be a recommended answer, strange.

I haven't met anyone who asked me to look for star fish, but I think it's normal, maybe someone used to raise a lot of star fish that didn't sell them, and they kept them for this task, and they still have them, so they can also be exchanged.

It's like there's something in the craft, and although there are no more raw materials now, there are still people who have those materials in their hands, so those synthesis methods haven't been deleted.

Hello from the owners.

This indicates that you are pressing too fast. 。

Click Wait for a dialog window to appear.

There is also a case.

The owner's backpack is full.

The system will receive the mail directly. 。

By chance it comes out, you can not sell.

I wish the landlord a happy game.

Still don't know how to welcome and ask for me.

It seems that as long as I have puffed chicken and mushrooms, I have never met a fish.
