INTERSTELLAR SPACE : THE SPACE BETWEEN STARS

We all are taught that a 3-dimensional area around us is called space. Yes, it's true that everything we see lies inside space.so what is interstellar space? In simple word, we say space between stars is called interstellar space but going some deep we'll find out that it the area where the sun's solar wind and magnetic field tends to be zero. It is separated by the region called the heliopause.

The first human spacecraft to enter interstellar space is Voyager 1.it is moving with a speed greater than 60,000km/h. 

We need to travel through interstellar space for visiting other stars but it'll not be easy for any civilization to conquer this danger.

Danger from interstellar space: interstellar space possesses a number of dangers like,

Cosmic rays 

Gamma-ray bursts 

Micro-meteoroid

Intense radiation 

And many more.

Through this, some will let out that then why we should leave the solar system, we are safe here. 

Then the only thing I want to say that, 

A ship in harbor is safe, but that is not what ships are built for.
