Lark, the other day I was listening to interview on BBC world (amazing interviews around 7am every morning while I am driving to work), famous astronomer (Forgot her name) was talking about working on a project searching for life on other planets. She said we are no where near having answers because it simply is too far away. They measure distances and orbits and observe what they could but their highest hopes are for eventually having more powerful telescopes. Until then a lot of it is just a hypothesis. It was so interesting to me how someone made it into a career. I was almost late to work because when I got to work, I didn’t want to leave my car during the interview!
