The Universe … It's Mind-Boggling!
We're getting so used to hearing gigantic numbers that a million begins to seem like no big deal. But try counting to a million sometime, and you'll realize how much it takes to make only one! When it comes to our universe, the numbers involved are truly phenomenal. Get your mind around these facts.
Notice the location of our Sun in the Milky Way Galaxy, indicated on the lower portion of the picture.
Located 2.5 million light-years away, the Andromeda is our largest nearby galactic neighbor. The galaxy's entire disk spans about 260,000 light-years, which means that a light beam would take 260,000 years to travel from one end of the galaxy to the other. By comparison, our Milky Way galaxy's disk is about 100,000 light-years across.
