25 Interesting Space Facts

Space FactsLet’s talk about “The Final Frontier”. You guessed it right, here are 25 interesting space facts.

Before we get started let’s make something clear. A lot of you folks ask where do space start and Earths atmosphere end? Well, Space is officially marked by the Kármán Line. This invisible line is 100 km ( around ~62.13 miles ) above the Earth.

Number 1
Our solar system takes a lot of time, or rather 225 million years to rotate around the Milky Way. Last time that Earth was in its current position, dinosaurs were just beginning to roam the surface. ( And we don’t mean theme parks either. )

Number 2
Ten thousand light years away from Earth, astronomers have discovered a massive cloud of alcohol spanning more than 463 billion km. It contains enough alcohol for 4 hundred trillion trillion cans of beer.

Number 3
Another cloud, made of water, is also out there. It has the equivalent of 140 trillion times the water in the world’s oceans, combined. The cloud is one hundred thousand times larger than our Sun.

Number 4
1 Light Year is approximately 9.5 trillion kilometers.

Number 5
There is a planet known as 55 Cancri E, that could be made of diamond. Due to immense pressure and temperature, along with the high carbon dioxide ratio of its host star, astrologers have hypothesized that this planet could be made of an outrageous amount of diamond. If true, it is estimated that this planet would be worth a mind-blowing 26.9 Nonillion U.S. dollars. To picture a Nonillion it is 269 followed by twenty-nine zeros, which is 384 quadrillion times more than the Earth’s GDP.

Number 6
About 1% of the static and white noise you get from not tuning an analog TV correctly, is actually radiation left over from The Big Bang. ( As in the explosion that created literally everything, not the TV show. )

Number 7
If you want to feel small, well, this is your fact. Our solar system, with the sun, planets, moons, billions of asteroids … literally, the whole thing fills less than a trillionth of our universe.

Number 8
Guess what guys?!? It’s a myth that exposure to space will make you explode. ( Yei! ) Don’t overreact too long though, because instead you will suffocate and die due to the lack of oxygen. ( Yeei … )

Number 9
Despite what the Star Wars universe states, space traveling through an asteroid belt is actually pretty safe. There are hundreds of thousands of kilometers between two objects inside the belt. The chance of hitting one is around one in a billion.

Number 10
As if you didn’t have enough stress in life, our Milky Way galaxy is on a collision course with the nearest galaxy called Andromeda. Fortunately for us, the impact won’t happen in the next 3 billion years, so don’t worry that much.

Number 11
Like a carousel run by a lunatic on speed, the Milky Way rotates at a speed of 270 km/s. So, the place you were an hour ago is now 1 million kilometers away.

Number 12
In space, if two pieces of metal touch each other, they will stick together. ( Like a married couple on a honeymoon.) This is a process called – cold welding.

Number 13
The Earth is surrounded by floating garbage. The planet has over 8 thousand objects orbiting around it, classified as “space junk”, which includes debris from spacecraft missions from the past. Still, the odds being killed by space debris are 1 in 5 billion. ( So, calm down all you paranoid people! )

Number 14
The energy produced by the Sun per hour is equivalent to 100 billion nuclear bombs. ( That’s enough to make Kim Jong-un very jelly indeed. )

Number 15
A soup can filled with neutron star material is not only not very tasty, but it will also have more mass than the entire moon. ( Because … SCIENCE! )

Number 16
The moon is not round, it’s actually more shaped like an egg.

Number 17
There are more stars in space than there are grains of sand on the entire Earth. ( Stars are also less likely to get on your sandwiches and ruin your food. )

Number 18
We hate to ruin your childhood, but stars don’t twinkle. They look like they are because the light is passing through layers that have different densities. That’s what makes it look like it shifts in brightness.

Number 19
Planets that have similar features to Earth, and are maybe capable of supporting human life are known as “Goldilocks planets”. It’s estimated that 500 million of those planets exist in our galaxy alone.

Number 20
Uranus was named after the ancient Greek god of the sky Ouranos. ( In Greek – Οὐρανός )  ( Damn .. space is so anal! 😀 ) It is the only planet which spins on its side, rather than on its axis. That resulted in a 42-year long summer and a 42 year period of darkness.

Number 21
The pressure on Mars is so low, that if you were to go there without a spacesuit, the oxygen in your blood will turn to bubbles and will cause immediate death. ( Hey, but on the bright side – Bubbles! Yei … pretty! )

Number 22
The word astronaut comes from the Greek word ástron (ἄστρον) which means “star” and nautes (ναύτης) which is referred to as “sailor”. “Cosmonaut” is based on the same principle, but with the indication that flights would occur in the cosmos ( near space ).

Number 23
NASA invested in a 3D printer that could make pizza for astronauts. ( Please make it public NASA we beg you! )

Number 24
The stars you see at the night sky might not be there anymore. Most stars are so far, that it takes millions of years for their light to reach us. So, you could be gazing at a star that died millions of years ago.

Number 25
The ARECIBO message is a one-time broadcast of a frequency modulated radio wave, sent into space with the series of encoded messages. Those messages could be interpreted by extraterrestrials. The message is made up of seven parts, goes for less than three minutes and includes the following information:
The numbers 1 to 10.
The atomic numbers of the elements Hydrogen, Carbon, Oxygen, Nitrogen, and Phosphorus, which make up DNA.
The formulas for sugars and bases in the nucleotides of DNA.
The number of nucleotides in DNA and a graphic of the double-helix structure of DNA.
A graphic of a human, the dimensions and physical height of an average man, and the human population of Earth.
Graphic of the solar system, indicating from which planet the message is coming from.
A graphic of ARECIBO radio telescope and the dimensions of the transmitting antenna dish.
