Galaxies

 This adventure will go through galaxies, they make up the Universe.

Galaxies contain stars, millions and trillions of them. Galaxies are like massive whirlpools of stars, they take unique shapes such as discs, balls or softly glowing clouds of light. Galaxies shine emitting visible and invisible radiation. This is usually visible light, which we can see, and ultraviolet, which we can't see.  So let's start looking at some examples.

The Andromeda Galaxy is the most distant thing we can see with the naked eye. It is 2.5 million light years away dnwe can only see it on the Darkest of nights. If you assume you travel at the speed of light you will take 50 years to get there, and another 50 to come back. You would be over 100 years old, but people on Earth will be 6 million years old, which means they are very very dead. That kids is relativity. 

The Whirlpool Galaxy is marked by thick black lanes of dust, which are called the spiralling arms. The arms give birth to Stars. Just like other Galaxy the whirlpool one is rushing away from us, this one at 500km every per second. When some Galaxies pass by the Whirlpool Galaxy their gravity can trigger star birth in the arms of the Galaxy.

Finally, lets us take a look at our Galaxy. The Milky Way. The Milky Way is a Whirlpool Galaxy, where we lie on one of the Milky Way's outer arms. The reason we call our Galaxy the Milky Way is because of the 'milky' stripe that we can see in the night sky, the inside of the Milky Way. The Milky Way is brighter in the Southern Hemisphere as the South Pole aims towards the bright galactic core.

This has been an extremely brief adventure on such a complicated topic. The aim of these adventures is to define Astrology terms, which will hopefully make my planets series easier to read for people with limited knowledge of Astrology.
