Episode Notes for
They Came From Outer Space!
Dr. Phil Plait
Are aliens from another planet visiting Earth? Astronomer and science writer Dr. Phil Plait seems a bit skeptical. In our discussion with Dr. Phil we cover a lot of interesting ideas including:
-
ALH84001 — what is it and does it prove aliens have come to Earth?
-
The role of extremophiles in the development of life on Earth?
-
The ratio of isotopes within a sample can tell us its origin — and what would we expect to see in an extraterrestrial sample?
-
Do amateur astronomers see more UFOs than average people?
Plus Dr. Plait tells us about his favorite monsters, favorite movies, and favorite paperback.
