When he says the sun is not visible from space, and you think wtf? go ahead and read down farther.
From what I see around the web the sun still shows on camera in space.

If you took a trip to the moon or outer space, the only glowing bodies you will be able to see are within our solar system. There won’t be a star in sight. Many find this to be interesting. Star light can only be viewed within Earth atmosphere.
The first astronaut that free fall from space after riding on a helium balloon in the 1960s was among the first to see this first hand. Just as he pierces through the stratosphere, the stars vanished from view. He was only able to see the glowing reflection of the earth and the moon. One would think that with the absent of distortion and pollution within the atmosphere, one should be able to see twice the number of stars. But this is not the case.
Why is this? We rely on our atmosphere and the sun to view stars images – with the naked eye. Outside our atmosphere we cannot see stars. Remember footage of the Apollo missions? Did you notice that they aren’t any stars in the footage? You cannot see stars from the surface of the moon because of the lack of an atmosphere.
To understand this effect it is important to understand how the eyes filter or focus an image, unfortunately, this is outside the scope of this article. However, for simplicity, we still use two theories of light; one depicts light as a wave vibration, and the other depicts light as particle. Wave-light demonstrates minute energy signature, while, particle light is more energetic. Of the two light concepts, star light has wave characteristics and therefore requires amplification before it can stimulate our optical sensors. This is where the sun and our atmosphere come into play.
Although the sun is on the other side of the globe- at nights, its ambient light is reflected and refracted off the atmosphere and encompasses the earth. We cannot see the sun at night but the sun makes it possible for us to see at light.
When the earth experience an eclipse of the sun, night on the opposite side where the eclipse occurs will experience an unusually darker night. This is caused from a reduction in the sun light reaching the atmosphere.
The next time you point your telescope to the stars or look up at the stars, it is important to remember that this is a view that can only be enjoyed here on planet Earth.
