Our knowledge of space is still very limited. Although research has been going on for more than half a century The universe is so big and full of mysteries We are at the beginning of everything.

Throughout all this research, there are many things we wonder about. For example, the topic of our content today is the smell of space. Is there really a smell in space? Even if there was, wouldn’t astronauts die if they took off their helmets and smelled it? Let’s explain one by one.

What does the room smell like?

Because there is no air in space like there is on Earth technically you don’t smell anything. If astronauts had tried this, they would have died anyway. But there are still molecules in space. During the Apollo mission, astronauts described in different ways the smell they smelled when they entered the spacecraft and took off their helmets.

They often smelled gunpowder, burnt metal and burnt steak. Even burnt almond cookies There were even people who made very specific definitions by saying: These smells obviously came from the clothes they were wearing.

So what is the source of the smell?

Scientists have two different theories about the source of the smell. First, when astronauts travel through space oxygen atoms sticking to your clothes and when they return, they are exposed to pressure and combine with other oxygen atoms, creating a kind of smokeless combustion and a burning smell.

The second is like burnt meat or burnt toast. polycyclic aromatic hydrocarbons (PAHs) found in charred foods also its rise in space. This situation usually occurs when stars explode while in space; in our world, this can happen when materials such as wood, meat, tobacco, and coal are burned.

Let’s see what happens in the future in this regard What surprising facts about space are we curious about? Will more emerge?
