Many things about outer space can be mind-boggling as well as exciting. The more you learn about it, the greater your desire to know more will be. If you let your imagination take its natural course, then you can ask yourself several questions about the situation in outer space. Well, here are some facts which should set on the right course to find out more.
Mum is the word
You might think that a lot of noise might be present in space because of the constant revolution of the various celestial bodies. However, outer space is completely free of all types of sounds. The simple reason behind this is that sound cannot travel without the help of a medium, and the vacuum present in space does not allow sound to travel.
Stars are truly infinite
Some people believe that they can count the total number of stars present in the galaxies. However, numerous attempts have been made to get the job done, and all of them have met with failure. It would not be wrong to say that the total number of stars cannot be counted.
The Sun is heavier than you imagine
All of you must be aware of the fact that all the planets of the solar system revolve around the Sun. And it is quite evident that the Sun is substantially larger than all other planets. But you will be surprised to find out that the mass of the Sun accounts for 99 percent of the mass of the entire solar system.
Talk about leaving footsteps
The Moon does not have an atmosphere leading to extremely slow erosion on its surface. So, people who have walked on the Moon will leave footsteps that will be present for millions of years to follow. It might sound unbelievable, but scientific research and evidence have already proven it.
