We live in a tiny part of the universe. Very few things in the vast universe have caught the eye of man. There are many mysteries in this which are beyond our comprehension. There is no end to the wonders of the universe. In this post we will discuss some of the amazing things about space.

1. Space is very quiet

No sound in space No. The whole space is absolutely silent. Medium is needed for the movement of sound. But since there is no atmosphere in space, no sound can be heard there. The question is, how do astronauts communicate with each other? Fortunately, radio waves can travel through zero. And with the help of this radio wave, the astronauts talk to each other.

2. How long will the footprints on the moon in the Apollo mission last?

How long will the human footprints engraved on the moon’s chest in spacecraft and Apollo missions sent to the moon at different times survive there? Since there is no air or water flow on the moon, they must remain intact. But in reality it will not happen. The weather on the moon is changeable. There are occasional small meteor showers. So it is normal for the shape of the moon to change. However, scientists estimate that the footprints of humans and the wheels of various spacecraft on the moon are less than 100 million years old. Survive!

3. The sun alone carries 99 percent of the mass of our solar system

The Sun, our nearest star, alone carries 99% of the mass of our solar system. Every second the sun converts about 600 million tons of hydrogen into helium. During this time about 4 million tons of particles are converted into energy as a by-product. When the sun, the star of nature, ‘dies’, it will turn into a ‘red giant’ or red monster that will cover the earth and everything on it. However, there is no reason to worry about this at the moment, because this will happen in the next 5 billion years Less likely.

4. Transfer of energy from the sun to the earth

More than the amount of solar energy used on Earth each year More Energy comes from the sun to the earth every hour.

5. Automatic welding in space!

If two pieces of metal of the same type touch each other in space, they are permanently attached to each other. Will be connected. This is known as ‘cold welding’. Since there is no air or water droplets in space, the metal molecules come in contact with each other and form bonds without hindrance. This is not the case with Earth’s climate, because there is so much in the atmosphere that molecules do not get this opportunity.
