Solar systems and galaxies, you can't really have one without the other. Galaxies are huge systems of stars and other interstellar material. We happen to live in the Milky Way Galaxy, which is a spiral galaxy. A spiral galaxy is a type of galaxy that has a spiral structure and a halo like component also. In the group of galaxies that the Milky Way belongs to it is the second largest galaxy to the Andromeda Galaxy. There are many galaxies all around ours that contain many different solar systems that we are currently unable to explore.
Our solar system is composed of the sun, nine planets (Well actually eight now because Pluto is not a planet anymore.), and many stars and moons. All the planets in our solar system orbit in an elliptical pattern, although some are more circular than others. We know that there are other galaxies besides our in space, but whether or not there are other solar systems has not been proven. Scientists are finding new evidence that they feel almost certainly has proven the existance of other solar systems. New discoveries like 51 Pegasi, 70 Virginis and 47 Ursae Majoris have forced many to believe that there are other solar systems orbiting a star. Advances in technology is the only way we could ever find out for sure, because as of right now we are limited to how far from "home" the earth we can travel in space.
I personally feel that space is such a weird and interesting topic. There really is so little that we actually know for sure beyond the clouds of our atmosphere. I feel that we all tend to forget how small and insignificant our world is compared to that of space. We are just one planet, in one solar system, of one galaxy, of thousands of other galaxies in space. When stated like that our lives seem pretty insignificant. The fun question associated with this topic is whether or not aliens truly exist. Which when you look at our solar system and how many other galaxies and solar systems there are, if each have one planet with life in them there must be billions of "aliens" we don't know about.

nice posting, jamie it was really detailed. yeah i definately feel the same about how big space is. it's sometimes too weird to think about, the world is pretty small compared to the rest of space.

Jamie,
Nice post! I really liked the facts you presented on the solar system. Space is pretty big, definitely...those aliens will probably come for us one of these days...

Great post Jamie! I was really impressed with how much you know about space. Way to put your foot down and say that pluto isn't a planet unlike what our topic said. Keep up the good work.

PS-see ya hot buns
Do you believe the possibility that Extra Terrestrials can exist? You are quite correct when you describe how big our galaxy is and how many other galaxies we know about but can't get to yet. But surely, with the expansiveness of the universe, other sentient beings must exist.
