Interesting and Incredible Space Facts that are Out of This World
This article includes some of the most cultural, historical and scientific facts about space that you probably didn’t know.
Space is a vacuum hence, it is completely silent with no sounds heard. There are no gases in space which are responsible for emitting sound waves hence, sound can cannot be able to travel in mars. Also, in order for sound to travel, there needs to be molecules to vibrate, but in space, there is large empty spaces between the starts and planet hence there will be no molecules to vibrate.
Because of its sheer size, no one knows the number of stars that are found in space. The immeasurable numbers comes about when the universe trillion galaxies is multiplied by the milky way’s estimated to be almost 400 billion.
Apart from planet Earth, Mars is another planet in the solar system that is believed to have life. Although no proof has found past or present life in mars, there are some evidence that shows the presence of liquid water which is host to microorganism. Besides, there was a research done in 1986 by NASA where they recovered fossils of living things in a rock.
Neutron stars which are the smallest and densest stars in the universe can spin as fast as 600 times per second. They can rotate up to 60 times per second when they are born from a star explosion. These stars have a radius of 10 km and they have a mass greater than that of the sun.
Space has thousands of other planets outside of the solar system. The planets which are outside the solar system are referred to as exo-planets and are in an orbit that is around a different star. Astronomers have confirmed at least 1800 new planets but most of them are hot gas and are not habitable like planet Earth.
The other pretty amazing fact is that one million earths would be required in order to fit the size of the sun. The sun which is at the center of the solar system takes up a large proportion of the whole solar system. It can therefore be able to accommodate millions of Earth’s.
On Venus, a single day is longer than an entire year. This means that it takes 244.7 Earth days for Venus to rotate on it axis just once. On the other hand, it only takes 243 Earth days for it to rotate on its axis once and this is what you need to know about the neptune facts.
Astronauts do not walk in space otherwise the skin of their feet will peel off. This is mainly because the skin becomes soft and the dead skin cells will start to flake off.
