So many stars!

On page 6 you learned that there are a hundred billion stars in our Milky Way galaxy.

On page 8 you learned that the Milky Way is just one of many galaxies.

Now think of this: There are about as many galaxies in the Universe as there are stars in the Milky Way!

Scientists estimate there are approximately 10,000,000,000,000,000,000,000 stars in the Universe. Thatís a hundred billion galaxies times a hundred billion stars in the Milky Way, equals ten sextillion stars in the Universe!

Another way to write this, using a kind of mathematical shorthand is:
1011 x 1011 = 1022. Of course this is approximate, but no matter how you look at it, it is a huge number.

You do not need to understand the math to know that the Universe is full of galaxies, and each galaxy contains many, many stars.
