Are you thirsty for knowledge about the unknown? There has been much research done in Space, but it isn’t enough to find out all of its secrets. Planets, galaxies, stardust, are some of the “space stuff” that fills the unlimited and unreachable space up there. We can’t know for sure whether there is life up there, or how many stars can be found. However, science has come up with many helpful discoveries. There are so many unbelievable facts that you didn’t know about. If you want to improve your current knowledge or get to know more, this article is for you!
Space is completely silent
Are you wondering what Space sounds like? Where gonna disappoint you a bit and tell you that Space is completely silent. Earth has plenty of air, which helps sound travel along, but, Space doesn’t have an atmosphere and is practically a vacuum. Sound is transmitted when the air molecules vibrate. This means that there is no way for sounds to travel around. This is the reason why they say that you won’t be heard if you scream in Space.
The footprints on the Moon will stay for long
On July 20, 1969, Apollo 11 made it safely to the surface of the moon. The “one small step for man, one giant leap for mankind” footstep will likely stay there forever. The Moon doesn’t have an atmosphere. This means that there won’t be any winds or erosion that can make the footsteps vanish. But this doesn’t mean that the Moon doesn’t get any erosion. Micrometeorites will slowly erode the surface, but the footprints are likely to stay there for about 100 million years. But footprints aren’t’ the only thing that they left. A small silicone disk with friendly messages from different countries was left as a gift from Earth to Moon.
Jupiter and Saturn experience diamond rain
Back here on Earth, rains are so boring. Did you know that it rains diamonds on Jupiter and Saturn? According to scientists, these two planets experience huge hailstorms of diamonds. The diamonds are large enough to be fitted into a glamorous ring, as they can reach up to a diameter of 0.40 inches.
NASA spacesuits cost US$ 12,000,000
Ever wondered how astronauts survive in space? They should thank their spacesuits for that. An average NASA spacesuit costs a stunning $12,000,000. They are very expensive because of their complex design. Actually, it is more like a small spacecraft rather than a piece of clothing. A spacesuit performs many functions such as protection from radiation, particles, providing oxygen and communication methods. On Earth, one suit weighs about 280 pounds. How can someone move with this huge weight on them? It’s pretty simple. In Space, the suit weights nothing due to microgravity in space.
Space has a specific smell
Ever wondered what Space smells like? There is no way for astronauts to smell space, as it is empty and air-less. But, we can rely on the items that are returned from Space. Surprisingly, astronauts claim that their suits smell a lot different when they return from a mission. They can describe the smell as “burnt” or metallic”. Scientists explain that this smell comes from the particles that came as a result of nuclear reactions in space. However, this isn’t the only “space stuff” fluttering around. Space can have other odors too, as it has a huge variety of different elements and particles.
An astronaut’s salary starts from $66,000 per year
Do you dream of becoming a fearless astronaut and discover the unknown space? Despite sounding like a cool job to do, it’s also well-paid too. The starting salary is $66,000, which can go up to $144,566 a year for seasoned astronauts. If landing a job at NASA is your dream, keep in mind that the basic knowledge requirements are biological science, engineering, physical science, or mathematics. The chance of being selected is 0.7 percent.
Venus is the hottest planet
The Earth has an optimal temperature for humans. But, have you ever wondered how hot or cold the other planets? Venus is the hottest planet in the whole Solar system, with a surface temperature of 863 degrees Fahrenheit. But, why does this planet absorb so much heat although it isn’t the one closest to the sun? The planet has a thick atmosphere of gases, which trap the heat in and don’t release it back. It’s hot enough to melt hard metal such as lead.
We can’t tell for sure how many stars are in Space
Space is practically limitless, so scientists can’t predict the exact number of stars. Our galaxy, the Milky Way has 200-400 billion stars. However, this isn’t the only galaxy in Space. Scientists estimate that there are billions of galaxies. If each one has the same number of stars, we can say that the stars are uncountable.
The planet 55 Cancri e is covered with diamonds
Did you know that there is a planet that is completely covered with diamonds? Although it sounds unbelievable, the planet called 55 Cancri e has a surface completely covered with diamonds and graphite. Sadly, it is about 40 light years away from our Earth. However, it is still visible in the Cancer constellation. This makes it possible for stargazers out there to spot it with their naked eye.
The Moon and Earth were one piece
A long time ago when it was still a young planet, the Earth was struck by an object. This resulted in a piece that broke off and fluttered in space, orbiting around the Earth. This piece is the Moon that we see today. The gravitational forces couldn’t split them apart, so the Moon remained in the Earth’s orbit.
We know that these mind-blowing facts left you speechless. Never stop learning and be eager to get to know more about the unknown! What do you think?
