Usually when scientists talk about the sky, we are thinking of Earth's atmosphere: the layer of gases that surround the planet. Itseems strange, but the atmosphere, or sky, doesn't actually "end". Instead, the higher up you go,the thinner – and less oxygenated – it gets. You don't have to go very high at all before you wouldn't be able to breathe properly. In fact, people going up tall mountains can have problems breathing, because the thin air at altitude doesn't contain enough oxygen.
At some height – most people say this is about 100km above sea level – the atmosphere becomes so thin that you could begin to think of yourself as being in space. Roughly speaking, this is where you need a vehicle to work more like aspaceship than aplane. People argue about where space actually begins – some people believe it's really 100 times farther from the ground at 10,000km abovesea level.
A: Our atmosphere doesn't end in one spot: it thins out the higher you get, until there is almost no air left at all. For simplicity, scientists say that the atmosphere ends at the Kármán line
Kármán line
The Kármán line (or von Kármán line /vɒn ˈkɑːrmɑːn/) is a proposed conventional boundary between Earth's atmosphere and outer space set by the international record-keeping body FAI (Fédération aéronautique internationale) at an altitude of 100 kilometres (54 nautical miles; 62 miles; 330,000 feet) above mean sea level.
It seems strange, but the atmosphere, or sky, doesn't actually "end". Instead, the higher up you go, the thinner – and less oxygenated – it gets. You don't have to go very high at all before you wouldn't be able to breathe properly.
The highest clouds are no higher than 12 kilometres (7.5 miles) above ground, so that altitude could be considered the “height of the sky”. Or it could be the boundary between the atmosphere and space—the upper limit for aircraft—which scientists give as 100 kilometres (62 miles) above ground.
The sky doesn't have “ends” in the conventional sense. One could only state that the sky has “ends” if the Earth were flat. But the Earth is a globe, and the sky is a hollow globe which envelopes the globe of the Earth. The outer limit of the atmosphere is the Exosphere.
Since you are surrounded by atmosphere, for you the sky begins where your eye ends and it extends as far as the atmosphere goes, or at least as far as there's enough atmospheric density to cause the effect.
Where does the sky end? If you were superman and you could fly straight up into the sky, the sky eventually turns into space. Scientists have to pick a place where space officially starts. One hundred kilometers (67 miles) up is a common dividing line.
there is no real distance between the Earth and sky but there is a distance between Earth and its horizon. If you are talking about the distance between Earth and the horizon then it is 12.2 miles(19.6km). Sky is actually space.
You will always see about half of the entire observable sky regardless of your location. It's only what part of it is visible at any moment what changes with location and time of day. But it will always be about half of the entire observable space.
The Earth's atmosphere is an extremely thin sheet of air extending from the surface of the Earth to the edge of space. The Earth is a sphere with a roughly 8000 mile diameter; the thickness of the atmosphere is about 60 miles.
The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space. It may also be considered a place between the ground and outer space, thus distinct from outer space. In the field of astronomy, the sky is also called the celestial sphere.
Technically, there is no such thing as a “sky”, so there's nothing to hold up. What we call the “sky” is merely a blanket of air around Earth. If anything, the blanket of air is held down by Earth's gravity, or else it would just float away into space.
Its such a unique place, you will feel like if you have come to another planet. Wherever the eyes can see, you only get to see "White"...a desert made by minerals, salts. Its really an amazing and unique place on this planet and a must visit whenever in Gujarat.
Nitrogen and oxygen make up most of the molecules in our atmosphere, but any gas or aerosol suspended in the air will scatter rays of sunlight into separate wavelengths of light. Consequently, when there are more aerosols in the atmosphere, more sunlight is scattered, resulting in more colorful skies.
The edge of space is 62 miles up. And the earth has a surface area of about 200 million miles. So the sky has a volume of a little over 12 billion cubic miles.
Space has no physical ground. Space is finite as the Universe is expanding, however with the accelerating rate of expansion which exceeds the speed of light, it is impossible to reach the edge.
The stars are rapidly disappearing from our night sky. A new study has found that the night sky may be brightening faster than once thought, and that has consequences for humans, ecosystems and more.
Not only does the earth rotate, but it also Orbitsaround the Sun. Where the Earth is located in its yearly orbit determines its seasonal constellations, because our perspective of the sky has changed.
Explanation. The best response is Shelley's: The stars are still in the sky above us, but we cannot see them. The reason we see stars at night is because our location on Earth is turned away from the Sun, blocking its light so that the evening sky is dark.
The stars are mostly the same as they were 2000 years ago. Enough that all of the classical constellations are the same. But some of them have in fact moved by measurable distances.
