Our last unit this year in science is space. I have studied space before, but that was quite a while ago, second grade to be exact. I have a few questions about space. I was wondering about what exactly the Hubble Space Telescope is and what it does. I also want to know when was it launched into space and how long it will stay in space. I was also wondering why some planets have atmospheres, and some don't. Shouldn't all planets have atmospheres? Also, why cant we see black holes? What makes a black hole, and why cant we see them? That is mainly what I am wondering about, and I hope my questions are answered by the end of the unit!
