We think of our world as filled with stuff like buildings and cars, buses and people, and nowhere does that seem more apparent than in crowded cities like Delhi, New York or Beijing. Yet all that stuff that makes up our everyday world is something just as important but far more mysterious – the space, in which all this stuff exists!
To get a feel for what we are talking about let’s stop for a moment and imagine; what if you took all this stuff away, we mean all of it, like the people, the cars and buildings, and not just the stuff here on earth but the earth itself. What if you took away all the planets, stars and galaxies, and not just the big stuff but tiny things down to the very last atoms of gas and dust; what if we took it all away, what would be left? Most of us think and would say nothing and we would be right, but strangely we would also be wrong!
What’s left is an empty space – in it are hidden structures, characteristics and forces as real as all the stuff in our everyday life. In fact, space is so real that it can bend, it can twist and it can repel. So real that empty space itself helps shape everything in the world around us and it forms every fabric of the cosmos. It carries forces that connect everything in our universe. It underpins our reality tying collectively everything that can be found in our conscious and subconscious realms!
We have listed the 10 interesting facts about space for you. Have a look!
1. Eerie silence everywhere
This might surprise a few readers but our space is a completely silent open field. Given the fact that the atmosphere is absent in space, there is no medium for sound to travel. Now, the question arises: how do astronauts communicate with each other? The answer is radio waves! They use radios to communicate with each other.
2. Number of stars in space
There is a very thin chance of predicting the exact number of stars in space. So far, scientists and astronomers have predicted 300-400 billion stars present in our galaxy only, i.e. the Milky Way. Remember this number is just a prediction. And there are many more unexplored, untapped and undiscovered galaxies where billions and trillions of stars may be present. So, it is hard to predict the number of stars in the space.
3. Relationship between Halley’s Comet and Earth-
Halley’s Comet was first discovered by Edmond Halley in 1705. The comet was last seen in 1986 and researchers claim that the next time we are going to see Halley is in 2061. It can only be seen once every 75 to 76 years.
4. Cost of a NASA Spacesuit
Before we spill the beans on what the cost of a NASA spacesuit is? We would like to reveal another fact that is related to the spacesuit. 70% of the total cost of the spacesuit consists of the control module and the backpack of the suit. And the cost of the NASA spacesuit is whooping 12 million dollars.
5. Neutron Stars and its rate of spinning
With a radius of just 10 km, Neutron Stars are the densest and tiniest stars in the space known so far. They can rotate at a speed up to 60 times per second after they are formed due to the core-collapse supernova star explosion. These can also spin at a maximum of 600 to 700 times per second.
6. Forming a permanent bond
In space, two portions of the same metal can permanently bond with each other. This phenomenon is called cold welding. This is possible because the pieces of metal don’t know how to separate from each other due to the absence of air and water.
7. Floating water
There’s a massive water vapor cloud that can hold up to 140 trillion times the mass of water present in the wholesome oceans on earth. This water vapor is around 10 billion light-years away and is regarded as one of the largest discovery of water by astronomers.
8. Moon and Earth were a part of each other
There exists an interesting theory where it is believed that there was a collision between a giant object and earth. This collision led to the falling off of a big part of the earth. And this abandoned part
became “the Moon.” This fallen piece then started moving around the earth due to its gravitational pull.
9. Footprints on the Moon
It is a known fact that the Moon has no atmosphere, which means there is no air and water to either erode or wash the footprints away. The footprints of the Apollo astronauts, along with other spaceships, rover crafts, and other debris, will stay as it is for millions of years to come.
10. Mars and its Everest
It is stated that a 600 kilometer wide and 21 km high volcano named Olympus Mons is still active on Mars. It is regarded as the tallest peak to exist on any planet known so far. However, the Rheasilvia central peak on asteroid Vesta holds the record of the tallest peak known to date.
One day on Venus equals more than 100 Earth days. On average, it takes around 115 Earth days to complete one rotation.
