Even though the outer space might be what surrounds the entire universe, we still don’t know that much about it. The utter vastness of the outer space is mind-boggling and to make things even more interesting, it’s constantly expanding. While the thought of being surrounded by something so large that scientists haven’t been figured out everything there is to know about it might be terrifying to some, it’s also intriguing to others. This is why we have decided to gather the top most interesting 20 facts about outer space and we are going to present them right now.
We are going to kick things off with something really interesting. Did you know that traveling through space will alter your DNA? This study was done with help from astronaut Scott Kelly (right) and his twin brother (Mark). When Scott Kelly came back to Earth, he was no longer identical with his twin at a molecular level.
The average temperature of outer space is lower than absolute zero. Not just that, but the temperature is slowly dropping because the universe is constantly expanding.
Another scary fact about outer space is that it is dead silent. Since there is no atmosphere, sound can’t travel and this means that if you are planning on becoming an astronaut, then you should be getting used to the sound of silence.
Do you feel like a day is not long enough for you to get done with work and then to also have some fun? This wouldn’t be a problem if we lived on Venus because a day on Venus lasts for an entire day on our planet!
Since we previously mentioned Venus, we need to present the fact that Venus and Mercury are the only two planets in our solar system that do not have any moons. In addition, there are a total of 176 moons orbiting the other planets.
An interesting fact about outer space that most people don’t know about is that it’s basically impossible to cry in space. The tears simply can’t fall because the lack of an atmosphere and instead, they will linger and build up in the astronaut’s eyes and then float away.
Here’s a scary thought for you. Did you know that astronomers have discovered a supermassive black hole that is moving through outer space at three million miles per hour? Let’s hope that it doesn’t find its way to Earth.
Try to guess how many stars there are in the known universe. If you guessed millions or billions, then you are wrong. There are so many stars in outer space that it’s impossible to count them all. NASA said that there are zillions of stars, yes you read that right, zillions with a Z not a B!
The footsteps left by the Apollo crew on the moon will stay there for more than 100 million years because there is no wind on the moon. Now, this is something that the astronauts can brag to their nephews about.
You probably already know that the sun is massive, but did you know that the sun makes up for 99% of our Galaxy’s mass? Another fun fact about the sun is that it fuses somewhere around 600 million tons of hydrogen to helium every second!
Somewhere around 1% of the static that we see on old TVs is residue from the Big Bang. This is the oldest electromagnetic radiation and it holds important information about the early universe.
Uranus is the famous blue ball that floats through the outer space but what many don’t know about it is that Uranus is tilted on its sides. Not just that but Uranus also two tenuous rings that look mesmerizing.
Here’s another interesting question for you, how fast do you think Neutron stars can spin? You might be surprised to find out that Neutron stars are the fastest spinning objects in the outer space and they can spin at 600 rotations per second!
Some of you might know that Mercury is the closest planet to the sun, but this doesn’t necessarily mean that Mercury is the hottest planet in our solar system. Venus is the one which holds this title with an average temperature of more than 450 degrees Celsius.
Mars is the only planet in our solar system where there is a high chance for humanity to start a colonization. A cool fact about Mars is that scientists have managed to find fossils of microscopic living things on a rock that was returned from the red planet.
There is a rare process called galactic cannibalism and just as the process’s name implies, a bigger galaxy will eat a smaller one. Let’s hope that our Milky Way galaxy never has to go through this process because otherwise, we would be doomed.
One of the side effects of exploring the outer space is that according to NASA, the calloused parts of their feet will fall off. Who knew that you can get a manicure in outer space?
Scientists report that if two pieces of the same type of metal touch ins pace, they will be bonded and get permanently stuck together. This incredible effect is called cold welding.
The largest asteroid in our solar system is called Ceres and it measures in at nearly 600 miles in diameter. Just imagine what would happen if Ceres started flying towards Earth!
Edmond Halley is the name of the astronomer who discovered the now-famous Halley’s Comet back in 1706. The comet orbited our planet back in 1986 and the next time that this will happen will be in 2061.
