A Space Vacation!
Come on a trip that's out of this world!
ATTENTION: DO YOU WANT TO GO ON A TRIP TO SPACE AND VIEW ALL KINDS OF THINGS IN THE UNIVERSE? THEN THIS TRIP IS PERFECT FOR YOU!
Below is a list of every type of thing we will be viewing.
I bet you want to know where stars come from. They actually come from something called a stellar nebula. In a stellar nebula it waits for just the right conditions. It waits for shock waves from nearby stars or supernova explosion. That causes ripples and matter clumps together. Gravity increases as more matter is pulled together. Once the temperature in the core reaches 18,000,000 (eighteen million) degrees a star is born. Stellar nebula are really cool to see and have amazing colors.
Main Sequence Stars:
On your trip there will be many stars to see. One type of star we will see is a main sequence star. Main sequence stars are in the longest stage of their life cycle. One of the average sized stars we will see is our very own sun! Won't that be fun? We will also see more massive stars. They might even be 10 times the sun.
Among the many types of stars we will see there will be some that are called red giants. Red giants actually come from average sized main sequence stars that are in the next stage of their life cycle. In this stage they will expand and become brighter and redder, even though they become redder that doesn't mean they are becoming warmer. They are actually getting colder.
We will also see some much smaller, white stars. They will be very warm, but gradually losing heat. White dwarfs occur after red giants. They are the end of the life cycle for an average star for example, our sun again. Once they burn off all of their heat like mentioned before they will turn dark.
If the mass of a star that had a supernova explosion is more than 3 times that of the sun it will completely collapse. What will be left is a black hole. Unfortunately, we cannot get close enough to view a black hole, because we will be sucked in. Not even light can escape its gravitational force.
In the universe there are groups of stars that are close together. They can have 12-1,000 stars. Contain hot, young stars, and due to this they don't last very long. Most are found in the spiral arms of our galaxy. Here's a fun fact: Experts estimate that there could be 20,000 open clusters in the Milky Way.
Globular clusters are usually older and can have 10,000 to 1,000,000 stars. (if you cant read those numbers its ten thousand to one million stars.) They are held together in a circular formation. People only know of about 200 globular clusters around our galaxy. That's still plenty to see.
Right now I bet you are really excited and thinking about this trip to space. Your only concern must be the cost. Well don't worry it will only set you back $1,000,000. Now there you go a perfect trip at a reasonable cost.
