Space is extremely mysterious. There are lots of space's facts that we haven't known and even haven't explored yet. The thing that how vast it is and what is there out there always arouse our curiosity.
Below will be incredible facts about space may surprise you
More than million Earths can fit inside the Sun
If you are considering how many Earths can fit in the Sun, the answer will be 1.3 million.
In fact, the volume of the Sun is 1.412 x 1018 km3 and the volume of the Earth is 1.083 x 1012 km3, so we will get the approximate number 1.300.000 if you divide the volume of the Sun by the one of the Earth.
However, the Sun is just a fairly average sized star, there are still enormous stars out there. The largest one is VY Canis Majoris that is said to be between 1800 and 2100 times the radius of the Sun.
Space is completely silent
No atmosphere exists in space, which means that sound has no medium or way to travel to be heard. In order to keep communication while in space, astronauts will use radios because radio waves can still work.
"How many stars are in space" is still a mystery
It seems to be impossible for human to predict just how many stars there are in such a vast space. Until now, that number is just estimated about 200-400 billion of stars and billions of galaxies, therefore, the stars in space are completely uncountable.
It is said that there are more stars in the universe than grains of sand on all the beaches on Earth. That’s at least a billion trillion!!
The Earth may be not the only planet existing life
During the years, it was believed that Earth was the only planet existing life. But recently, NASA revealed its strongest evidence yet that there is intermittent running water on Mars. That shows a hospitable ability for life existing on Mars.
The sunset on Mars is blue
Earth and Mars are like two contrasting worlds. Mars is a red planet. Earth is a light blue dot. Mars is a cold desert. The Earth is full of water and life. But there is an even more strange difference: The sky on Mars is red, while its sunset is blue.
