If there is no atmosphere in space, then how come...?

Be proud of yourself, you found a mistake that slips past some of the most rabid trekkies.\nBut now I think of it, the parts of the engines themselves might be able to make a whoosing sound that would travel through the walls of the ship and be heard inside. But you're right, you shouldn't be able to hear it from the view of the ship they have in the opening sequence.

No oxygen in space. Need to bring or make your own.\nNo gravity or very weak affects the human body in many ways, one big is it weakens ones bones(and muscles).

The earths atmosphere\n\n\nMy first thought was not formal. What I thought when I read your question is that nothing is between heaven and earth that "the heavens" come down and touch the earth.

well unfortunately, outerspace is a whole lot of nothing, so it doesnt have to take up any space.  granted there are molecules floating around out there, but for the most part there isnt any matter in empty outer space

It's really not a matter of distance from the sun, it is a matter of space being a vacuum.  The other issue is that "air" is not normally present or contained in a spacecraft.  Most spacecraft storing gasses contain hydrazine for propulsion.  If you are talking about a manned spacecraft such as the ISS then you would be talking about liquid oxygen.  If the oxygen tank ruptured pressure would go to zero, the liquid would instantly boil and the resultant gas would dissipate.

Good question. I never understood that, either. Maybe something to do with the government or the some atmosphere changes? I have no idea, really. Sorry.

The Outer space does posses gases, but the vaccum is present because of the incomrehensible size of the universe. Had gases  such as Hydrogen and Helium not been present, there wouldn't have been a sun or nuclear fusion... vaccum indicates absence of matter. It becomes a matter of perspective whether you stand on earth and say that the galaxy andromeda is in outer space but earth is not.. when a hypothetical being on andromeda would say that earth is in outer space but andromeda is not... ;)

Space is technically a vacuum, hence void of any matter, invisible, see-through, like a very clean window! That's also why they placed the Hubble Telescope in orbit, out of the atmosphere.  The atmosphere seriously effects a telescope's ability to 'see' far into the universe.  It's essentially like looking through a dirty glass, because of all the particulate.\n\nSo,\nIn space no physical matter, no perception of light.  There is no air and/or physical matter for the light to bounce off of and around etc..\nIn other words, the reflections of light from objects creates the effect we perceive as light, or being lit-up.  \n\nAny solid will also be illuminated by the sun, in space. Proof of that is the moon, or any other planets visible by eye or telescope.  \n\nOur atmosphere (air is matter too) gives the appearance of being "lit" up, and all the solids on earth reflect that light, causing the effect of being "lit up"..\n\nTry this.  Go into a completely dark room, and turn on a good straight beam flashlight.  Can you see the particulate in the air?  The little lighted particles?  If they weren't there, all you would see is the white dot on the wall, that the light creates.  The reason you can put your hand next to the beam and still see it is from the reflection on the wall, AND the particle matter in the air, which causes light to stray onto your hand.  In this case it's more the reflection, but both aid in you seeing your hand..\n\nNow, take that HUGE flashlight in the sky *sun*, and apply that to what you have asked!

In earth's atmosphere there is gravity that comes from the core of the earth. In Space, there is no gravity or "Zero Gravity", which means space is does not move except for the obitization of the planets around the sun. But, space is endless, so, we could be falling but never hit because of infinate space. but i do not think we fall.

The air gets thinner with altitude and with that so does the temperature. \n\nBesides, to say that you're approaching the sun when you've not even left earth's atmosphere is like saying you're approaching New York when you've only checked in your luggage at Heathrow.

It gets colder as you go up through the troposphere because the air is "thinner".\n\nThere is less atmosphere here due to less gravity.\n\nB/c there is less air, there will be less heat. Air is an insulator that holds heat. Less air = less heat.\n\n:)

no atmosphere...wink,wink. How ya doin' buddy?

THERE IS NO SUCH THING AS A TRUE VACUUM... PERIOD!\n(exerpt from a previous answer)\nContrary to popular belief, empty space is not empty, and it is certainly not a vacuum. In fact, a true vacuum has never been created, anywhere, where the atomic count is zero.\nresearch it, its true.\n"Empty" space actually contains an average of 1 hydrogen atom for every 32 cubic centimeters of space, this data is per NASA.\n\nIn our own Milky Way, space is more dense with 1 hydrogen atom for every 1 cubic centimeter.\n\nOne day the misinformation of space as a vacuum will finally die out.\n\nSo YES, a dead body would decompose eventually, How long would depend on the bodies proximity to other planetary bodies such as the sun, the earth,etc., and how long it stayed in space before falling into an orbit around one of those entities.\n\nspread the knowledge

If you were able to create an Earth-like atmosphere on a planet, then it would scatter sunlight just as Earth's does and the sky would be blue and bright when the sun was on it. If you just have a pressurized dome (a more technologically feasible situation), there wouldn't be enough air to significantly scatter light and you could look out of the dome and see black sky.

Empty space itself cannot have a temperature.  However, if you put a physical object into space, it will reach a temperature that depends on how efficiently it absorbs and emits radiation and on what heating sources are nearby.  For example, an object that both absorbs and emits perfectly, put at the Earth's distance from the Sun, will reach a temperature of about 280 degrees.  If it is shielded from the Sun but exposed to interplanetary and interstellar radiation, it reaches about 5 degrees.  If it were far from all stars and galaxies, it would come into equilibrium with the microwave background at about 2.7 degrees.\n\nSpacecraft (and spacewalking astronauts) often run a bit hotter than 280 K because they generate internal energy.  Arranging for them to run at the desired temperature is an important aspect of design.

Contrary to the above answers, you could smell in space. However you would need a really strong smell to do so. \n\nUs humans need to draw large amounts of the air that  contains an odour through our nose in order to be able to detectit. Space of course contains no air, so to be able to smell anyhting in space the odour itself would need ot be very concentrated.\n\nBut certainly if I opened a bottle of ammonia 3 inches under your nose in space you would smell it just fine.\n\n>>>>>But in space, there is no atmosphere for them to\n>>>>> disperse in, so there is no way for the "smelly"\n>>>>> particles to diffuse to your nose.\n\nUnless the gravity is EXTREMELY dense , the smell is EXTREMELY faint or the the conditions are EXTREMELY cold those molecules will diffuse faster in space thanon Earth.\n\nAs they are liberated from the source they must have achieved vapourisation temperature. Therefore they already have significant velocity. The odour molecules will be colliding with each other and undergoing all the normal interactions. As they disperse more the velocity will remin unaltered but the movement will become linear rather than random brownian movement as they cease to interact. But that would only make the dispersion faster, not slower.\n\nIf you don't believe me consider this. If you placed a bowl of water on the surface of the moon what would happen?  If lack of an atmoosphere stops volatile molecules from dispersing how does the water evaporate in space? Now what would happen if you placed a small amount of ammonia in that water? If the ammonia molecules are dispersing far enough to allow evaporation then why would they not disperse further?\n\nFor all those who said that you can not smell in space this is the critical quetsion to answer. If you accept that ammonia, chlorine and other odoriferous materials can evaporate in space why dont you also believe they are capable of diffusing?\n\nAnd if you believe they are capable of diffusing why do you believe the ofactory glands couldn't react to them?\n\nAnd if you believe the olfactory glands could react to them wwhy do you believe that the neurons couldn't pass that to the brain?\n_______\n>>>>>This answer more pretains to solid 'smell' particles\n>>>>> rather than 'smelly' gasses.\n\nI'm not quite sure what that means. The only 'solid smell particles' are things like smoke. I'd guess that 99.9% of the odours humans detect are gaseous: perfume, ammonia, body adour, food and so sorth. All are caused by volatile materials, ie they exist as gas when we smell them.\n\nYou are correct that the tiny number of odours actually caused suspended solid particles could not travel readily in a vacuum. But most odours would travel further and faster in a vacuum.
