How does the space in the universe smell like?

Space in the universe contains many of the combustion byproducts that are compounds of polycianic aromatic hydrocarbon (polycianic aromatic hydrocarbon-PAH). PAH compound molecules appear to be everywhere in the universe and have a characteristic flavor.

In the air there are many flavors, but mainly the smell of PAH.

Louis Allamandola, director of the Institute of Astrophysics and Chemistry, said that these compounds are also on the list of the earliest substances on Earth, so it is not surprising that PAH is found in coal, oil and even food.

The taste in the air is very different from the earth. Three years ago, NASA asked for help from Steven Pearce, a perfume maker to simulate the smell of air for the training of astronauts. Pearce said the smell in the air resembled the smell of gunpowder.

Allamandola explained that the smell in our solar system is especially spicy because it contains a lot of carbon and less oxygen, and for example 'just like a car operating in an oxygen-depleted state, it will appear soot. and bad smell. The stars contain a lot of oxygen, however, it tastes like the smell of a charcoal grill.

Once you leave our galaxy, you can meet interesting smells. In the black pocket of the universe, molecular clouds contain tiny dust particles with odors, wafting over the sweet taste along with the odor of sulfur's rotten eggs'.
