In this special article of Info Techs we will talk about space technology or in other words we will talk about space. We will discuss some interesting facts about space.
But before that I would you guys to check out this awesome coat from Gearbest it is really amazing. It is pretty warm and looks pretty amazing.
Let’s start our topic.
The first fact about space I will like to discuss is that space is silent. There is absolutely no sound in space. Sound waves need some medium to travel and there is no such medium in space there is only vacuum. So, the videos you see about space in which there is some background music it is not possible space is completely 100% silent.
The next fact about space I will like to discuss is that in our universe there are so many stars and so many galaxies that it is not possible to count them. NASA have said that if we multiply our milky way some millions times we can estimate the total number of galaxies according to that estimate there are around one zillion galaxies. The national university of Australia have said that there are around 16 trillion stars.
The next fact about space is that the foot prints of the astronaut who went first time on moon are still there and they will remain there for millions of year it is possible. The reason is that there is no water or air on the moon there is no environmental disturbance so the things the foot prints of the astronauts they have left there will remain there for millions of years. Micro meteoroids do fall on moon which changes things up to some extent but it is very rare that the meteoroids will fall on the exact same spot on which astronauts have left some thing.
The next fact about space is that the 99% of the surface of our solar system is sun. The sun is very huge and if we compare it with all the other planets of our solar system we will find out it is the 99% surface of our solar system and 1% are all the other planets.
The next fact about space is that our planet survive with the energy or heat coming from the sun. The ultimate source of energy of every living being on this planet is sun. Sun put so much energy on earth in just one hour that we can utilize it for at least one year but we are unable to utilize it completely. The use of the solar energy is increasing 20% every year.
The next fact about space is that if two metals of same type collides in space they will form a bond and they will be attached with each other. The reason is that there is no third thing between two objects in space which can separate them. It is a really interesting fact about space which most of people don’t know.
The next fact about space is that one day of Venus is greater than one year on earth.
