Is there no sound in space?
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.Is there actually no sound 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.Can you hear an explosion in space?
In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically 'explode'.How cold is space?
According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).What would space smell like?
Astronaut Thomas Jones said it "carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous." Tony Antonelli, another space-walker, said space "definitely has a smell that's different than anything else." A gentleman named Don Pettit was a bit more verbose on the topic: "Each time, when I ...Top 10 Terrifying Signals Heard By Submarines
Can you smell a fart in space?
Therefore, the fart will not be smelled by the astronaut, although they may marinate in it for a time. When astronauts are not in the space suit and floating about, the fart smell is exaggerated by the lack of airflow from the recycled air used and its inability to mask any smell.Why is space completely silent?
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.Can you play music in space?
As there is air on a spacecraft, musical instruments should still work. However, it might not work if you try to play outside of a shuttle or space station. On a violin or guitar, the strings would vibrate without producing a sound.Do we age faster in space?
It's long been known that exposure to radiation damages DNA, but a new study has found an additional risk for astronauts: DNA replication is more prone to errors in microgravity.Can there be fires in space?
In space, of course, you can't have any fires because there isn't any oxidizer (i.e. oxygen) to sustain the combustion process.Can you talk in space?
When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.Why is space dark?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.Is space completely dark?
Above the Earth's atmosphere, outer space dims even further, fading to an inky pitch-black. And yet even there, space isn't absolutely black. The universe has a suffused feeble glimmer from innumerable distant stars and galaxies.Why is space so cold?
In space, there is no air or water, so the only way to lose heat is by radiation, where your warm and wiggly atoms release energy directly into space. This is a slow process, so you'd die of oxygen deprivation long before you'd notice the cold!Can astronauts have alcohol in space?
Alcoholic drinks are generally disallowed in spaceflight, but space agencies have previously allowed its consumption. NASA has been stricter about alcohol consumption than the Roscosmos, both according to regulations and in practice. Astronauts and cosmonauts are restricted from being intoxicated at launch.How much do astronauts get paid while in space?
Civilian. The pay grades for civilian astronaut candidates are set by federal government pay scales and vary based on academic achievements and experience. According to NASA , civilian astronaut salaries range from $104,898 to $161,141 per year.Does water freeze in space?
Does it freeze or boil? The surprising answer is it does both: first it boils and then it freezes! We know this because this is what used to happen when astronauts felt the call of nature while in space.Is space actually colorful?
Galaxies are not actually as colorful as we think they areSpace emits a range of wavelengths of light, some we can see others we can't. The majority of emissions are of red and blue light which are easily visible to the human eye but there are also UV, X-rays and gamma rays which are invisible.
Is space hot or cold?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).Why can't you see the sun in space?
In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together.Why Earth looks blue from space?
Seen from space, the Earth is blue. The Earth has been blue for over 4 billion years because of the liquid water on its surface. How has the Earth managed to sustain liquid water on its surface for such a long time? There is only one known planet with permanent bodies of liquid water at its surface: ours.What colour is space?
If we add up all the light coming from galaxies (and the stars within them), and from all the clouds of gas and dust in the Universe, we'd end up with a colour very close to white, but actually a little bit 'beige'.How do astronauts sleep?
The astronauts sleep in small sleeping compartments by using sleeping bags. They strap their bodies loosely so that their bodies will not float around. In the zero-gravity world, there are no "ups" or "downs". The astronauts can sleep anywhere facing any direction.Does the moon make noise?
However, the Moon is in space, and space is mostly a vacuum (there are always some atoms floating around, but they are VERY far apart and don't interact with one another). Thus there is no sound on the Moon.
