Due to the sheer size of space, it contains trillions of objects and galaxies that are out of this world, here are some incredible facts about space.
The first awesome fact about space is that it is completely silent. Unlike Earth which has atmosphere, Mars does not have air or gases that permit sound to travel. 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.
There are so many stars in the universe that are uncountable and no one knows the exact number. The universe is estimated to have 10 trillion galaxies and when that number is multiplied by the milk ways estimated 400 billion stars, then you a very large number of stars that is uncountable.
Another coll fact is that planet Mars shows some similarities with Earth and is believed to be hospitable to life. In order for life to thrive, there needs to be water and there are some research that have proven presence of a long supply of water in Mars. With the aim to determine whether life ever evolved on Mars, NASA conducted some research and found fossils of tiny living things recovered 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.
It has been determined that the sun is 300,000 times bigger than the Earth, hence, one million Earth’s will be needed in order to fit in the sun. The sun’s mass accounts for 99.86% of the entire solar system. Therefore, one million Earths will be needed so that it can be the same size as the sun and it is therefore wise to understand the uranus facts.
On Venus, a single day is longer than an entire year. 244.7 Earth days is the length of time that it will take Mars to rotate around the sun. However, it takes 243 days to rotate on its axis which is less compared to Earth’s 365.
When astronauts go to space, they do not use their feet to walk because the skin of the feet may peel off. Due to the micro-gravity environment, the skin of the feet becomes soft and starts to flake off.
