For the knowledge seeker.
The close-up of the Andromeda Galaxy from the Hubble Space Telescope shows how many stars there really are.
Now this is just a small part of ONE Galaxy in our universe, our solar system has 1 star/sun with from what we understand nine planets, one we know can support life. So the fun question is if each dot in this picture is a star or sun, how many planets COULD that star/sun have? and how many of those planets COULD support some kind of life?
