Morgan+and+Haley

Here are Morgans three questions. 1. Will the sun ever stop shinning? 2. How many stars are in a galaxy? 3.How many people have been on the moon?

1. Yes, the Sun will stop shinning but not for a very, very long time. Stars shine because a huge amount of energy is created in their cores by a process called nuclear fusion. Nuclear fusion happens when lighter elements, like hydrogen, are combined into heavier elements, like helium. In about 5 billion years, the hydrogen in the sun's core will run out and the sun will not have enough fuel for nuclear fusion. So, in about 5 billion years, the sun will stop shining.

2. The best estimates suggest that the Milky Way contains about 500 thousand million stars. There are way to many stars in the Milky Way to count. The galexy is to large so know one knows exactly how many stars are in the Milky Way. Stars are made up of big balls of gas.Some stars are big and some stars are smaller.
