Where Are The Aliens? | Cosmic Vistas | Spark

Explore the question of the Fermi paradox: Given a few reasonable assumptions about the chance of life arising elsewhere in the universe and the distances between the stars, why haven’t we uncovered another civilization?

Season Four of Cosmic Vistas zooms in to focus on some familiar solar bodies within our reach. How well do we really know our celestial neighbours such as Saturn and Mars? What do we have yet to learn? With the help of satellite technology and the incredible shuttles that put them into orbit, many questions about our solar system's past and future are finally being answered by science.
