What does space smell like?
Smell is an indispensable part of our life. The smells we smell on earth are odorless, if we can breathe in space, so I asked the question, what does space taste like? My initial idea was: The smell of space is pungent. Because there are 92 chemical elements on earth, and these elements also exist in space, one few, one many. In addition to the 92 elements, there are various subatomic particles in space. These particles have also been found on earth (or made in particle accelerators). There are so many material in the space, so I thought space smell like pungent. After my research on this issue, my final opinion is: smell of metal, or charred steak.
My question is: what does the space smell like?If I want to know what space smell like, I need to know what’s in it and what does space contain. Through searching the information, I know: There are Jupiter, Saturn, Uranus, Venus, and so(*1) There are an infinite number of planets in space. Jupiter smell of which has been likened to bitter almonds, or marzipan. Uranus has no smell. Venus smells like rotten eggs.(*2) So space smells different. And space contain mostly hydrogen atoms, sulfurous. There are lesser amounts of helium and lithium atoms. This question reflects the smell of space.
The third small question, is Does temperature affect smell? On earth, temperature affects smell. For example, when it rains, the smell is moist and fresh. On a hot day, the smell changes with the temperature. In space, The temperature in outer space is 2.73 Kelvin (-270.42 Celsius, -454.75 Fahrenheit).(*1) The temperature in space is minus 272 degrees Celsius, I think the temperature will affect the smell. The fourth small question, is Disappear stars have any effect on the smell of space? I think Disappear stars have effect on the smell of space. There is a special smell at the edge of the universe. This smell smells like the smell of high-speed combustion of oil in cars, that is, the smell of hot metals and diesel. This strange smell exists in The causes of the edge of the universe are mainly from those dying stars. After my search, I finally came to the answer: space is the smell of burning metal. The last question is: Disappear stars have any effect on the smell of space？ Disappear stars have effect on the smell of space. There is a special smell at the edge of the universe. This smell smells like the smell of high-speed combustion of oil in cars, that is, the smell of hot metals and diesel. This strange smell exists in The causes of the edge of the universe are mainly from those dying stars.(*2)
Conclution: Through my search, space smell like the smell of burnt metal. Space contains mostly hydrogen atoms. There are lesser amounts of helium and lithium atoms. There are so many planets in space. Such as: Mars, Jupiter, Uranus, Venus… Every planet has a different smell. So they affect the smell in the space. I think the temperature will affect the smell. The temperature in space is minus 272 degrees Celsius, Although people can’t breathe normally in space, their olfactory receptors become more sluggish. So that’s why People experience the same smell differently in cold and hot environments. The last question is “Disappear stars have any effect on the smell of space?” The short answer is dying stars. Louis Allamandola, director of NASA’s astrophysics and astrochemistry lab, says that as stars combust, they release polycyclic aromatic hydrocarbons, which explains the smell. These molecules can also be found on Earth in things such as soot, car exhaust, burnt toast and charred meat. When the doomed planet disappears, there is a smell of burnt metal. And that’s the answer to my question. Space smell like burnt metal.
