Sorry I can't blogwalking :(
Im following SNMPTN test . Hehehe
Tonight Im enjoying the scenery in front of my room .
When I heard one broadcast on television about Belt of Venus .
Views of the sky are very nice .


What is Belt of Venus ?
Belt of Venus (the name of the Roman goddess Venus) is a brownish pink border which separates the image file that dark earth, the sky above it .
Now I will explain about the Belt of Venus :
Belt of Venus is actually the shadow of the Earth that appears on the eastern side or the direction opposite to the direction of sunset . This natural phenomenon will look very good when the sky was cloudless, but very dusty , especially at twilight , after sunset . It usually occurs 10 - 15 minutes after sunset .
At the time, the earth's atmosphere is sinking sun casting light , and appear as light red (pink) and brown , which appears in the sky and the horizon , about 50 - 100 miles from where we stood .
NB : (Try viewing , you may also be seen in the sky !)


So how do we know about the Belt of Venus ?
Let's see explanation below ...


Did you know ??
Whereas 3 minutes after sunset , it would look like a form of "ribbon" pink began to dim , but with the lighter color / clear . After that, who looked only a thin pink ribbon on a blue sky .
Then, 6 minutes after sunset , will appear dark blue ribbon under a pink ribbon and the shape becomes more clear , rounded shape with the center seemed higher than the edges .
Then, 15 minutes after sunset, the pink color disappears. But the shadow of the earth can still be seen in the east of the hump, in the sky that looked more dark, along the horizon - the exact opposite of the normal situation, where the sky light and dark along the horizon toward the zenith .


Ah, I think you must now... Zenith is a point in space located directly above the observer . Like this picture..
Do you know about "why the sky red at dawn or evening?"
Many people who say that when the sky is red , we should not see the sky because it sill cause eye pain .
Let's discuss why the sky is red in science !
There are 2 reason why the horizon at dawn or evening :
  • First is the strong scattering of blue light , which through the thin air layer when the sun is low . 
  • Second is the "Extinction" caused by dust particles .
This is what causes the red color spectrum is dominant .
Done for the discussion of the Belt of Venus .
What do you think ? Did you ever see it ?
