Outer space or the universe is a vacuum that is outside the Earth’s atmosphere. When you look closer, outer space holds a lot of celestial objects such as planets, stars, meteors, galaxies, and mysteries inside.
Currently there are many space missions carried out by various countries to reveal and explore many things in outer space, so the goals are different. To get to know more about the existence of outer space, you can listen to some of the following interesting facts.
1. There is no sound in space

You might be curious about what sounds actually sound like in outer space, because is it possible that the sound is similar to the sounds of nature on Earth or is it actually different. Reported Cosmos Magazine, it turns out that in space there is no sound at all that can be heard. This is because sound travels through particle vibrations, while outer space is a vacuum that cannot transmit these sounds.
2. Outer space has no end

If you visit a place, maybe you will realize that these places have their own, very distinctive aroma. It’s the same as outer space which turns out to have an odor, but the nose cannot smell it directly because the human nose cannot work in an airtight space like outer space. Reported BBC Science Focus Magazine, many astronauts working on the ISS space station report that they smell a metallic odor on their spacesuits.

You may be wondering what temperature actually outer space has, maybe it actually has hot, cold, or even changing temperatures like the temperature on Earth. Reported All The Science, it turns out that outer space has very cold temperatures, which can reach minus 270 degrees Celsius. Even though it’s cold, the wide-open exposure to radiation in space makes it a dangerous area, so astronauts must be careful.
