NGC 7331 and Beyond
This is the galazy NGC 7331. It is most often compared to our Milky Way galaxy because of it's apparent likeness -- Being a spiral galaxy and roughly the same size.
It is the beyond I want to focus on, though. This galaxy is about 30 million light years away from us. However, if you can see, just above NGC 7331 several distinct galaxies. They are roughly a tenth the size. This means that they are about 10 times further than NGC 7331 is from us. 300 million ly away!! Now, look at the little dots. Every dot is a galaxy. Some are even 100th the size of 7331. That's 3 billion light years away!!
It is so unbelievable how vast this universe is!!
