What college major is best for me?

What major is best for me? I love space, but I don't want to design planes or spacecraft. I am fascinated with the very big and very small (from black hoes to the nanoscale). I am good at math and love to discover and organize. I read a lot, too. I looked into liberal arts, but decided against it since I already have work published writing without a BA. I tried Aerospace Engineering but wasn't in love with it. I was going to try Astronomy but heard I'd only get a job as a professor or working at an observatory.
