Actually there is no air as we know it in space. On our earth, air is a mixture of gases, mostly nitrogen and oxygen and some other gases. When you go higher and higher in the atmosphere, there are less and less air molecules. Space is almost a perfect vacuum, but gas and dust particles do float around out there..
Keeping this in view, are there molecules in space?
The molecules of outer space: Astronomers have found that the dark regions of interstellar space are teeming with molecules, many formed by unusual chemical reactions that rarely occur on the Earth. and planets. many carbon atoms as both chains and rings.
One may also ask, what happens to air molecules in space? Those air molecules just fly apart. There's effectively nothing in their way so they just keep going. Depending on their position in Earth's gravitational field, they will either fall back into the upper atmosphere and mix back in, or they will simply keep going.
Keeping this in view, is air available in space?
In space, no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum. 'Outer space' begins about 100 km above the Earth, where the shell of air around our planet disappears.
How cold is space?

Related Question Answers
Can there be fire in space?
Recent tests aboard the International Space Station have shown that fire in space can be less predictable and potentially more lethal than it is on Earth. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire.Is there oxygen in space?
Individual atoms of oxygen are common in space, particularly around massive stars. But, molecular oxygen, which makes up about 20 percent of the air we breathe, has eluded astronomers until now.Who discovered space?

Is water a molecule?
Compounds contain two or more different elements. Water is a molecule because it contains molecular bonds. Water is also a compound because it is made from more than one kind of element (oxygen and hydrogen). This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.Is there gas in space?
Much of the space between the stars is filled with atomic and molecular gas (primarily hydrogen and helium) and tiny pieces of solid particles or dust (composed mainly of carbon, silicon and oxygen). In some places this interstellar material is very dense, forming nebulas.Can you see a molecule?
Microscope Sees Molecules for First Time. That's what it's been like trying to take a picture of a molecule. Advanced electron microscopes can get amazing resolution, fine enough to see inside an atom, but molecular bonds usually aren't strong enough to hold up to their scrutiny.Is space a vacuum?
Outer space has very low density and pressure, and is the closest physical approximation of a perfect vacuum. But no vacuum is truly perfect, not even in interstellar space, where there are still a few hydrogen atoms per cubic meter.What does space smell like?
When astronauts return from space walks and remove their helmets, they are welcomed back with a peculiar smell. An odor that is distinct and weird: something, astronauts have described it, like "seared steak." And also: "hot metal." And also: "welding fumes." Space, Jones elaborated, smells a little like gunpowder.In which planet there is no air?

How old is space?

Can you hear in space?
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.Does Moon have air?
On the moon, there's no air to breathe, no breezes to make the flags planted there by the Apollo astronauts flutter. However, there is a very, very thin layer of gases on the lunar surface that can almost be called an atmosphere. Technically, it's considered an exosphere.Why can't humans breathe in space?
Whatever you do, don't hold your breath! The vacuum of space will pull the air from your body. So if there's air left in your lungs, they will rupture. Oxygen in the rest of your body will also expand.Where does space start?
Outer space does not begin at a definite altitude above the Earth's surface. However, the Kármán line, an altitude of 100 km (62 mi) above sea level, is conventionally used as the start of outer space in space treaties and for aerospace records keeping.What is outside the universe?
But “infinity” means that, beyond the observable universe, you won't just find more planets and stars and other forms of material…you will eventually find every possible thing.What does outer space look like?
Space is full of light, but it doesn't look like it. The color black usually signals the absence of light. But inside the solar system, space is filled with light.What happens to a dead body in space?
If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.How do you get air in space?
The short answer is the astronauts and cosmonauts (that means a Russian astronaut) bring oxygen from Earth, and they make oxygen by running electricity through water. This is called electrolysis. The air and water on the Space Station all originally came from Earth.Where does air end in space?
But the atmosphere doesn't stop there — it continues on, gradually thinning out for thousands of miles. The final layer of the atmosphere, the enormous exosphere, continues until around 6,700 miles (10,000 km) above the surface of our planet (and some say even further).
