Louisa Preston is an Astrobiologist and TED Fellow based at The Open University, UK. She works with microbes that live in the most extreme places on Earth as analogues for life we might find on other planets. She studies how life gets trapped inside rocks and minerals, how it can be identified, and therefore how and where we should be looking for life on Mars. She received her PhD in Astrobiology from Imperial College London, UK and spent time at Western University in Canada working on analogue space missions before moving to The Open University.

Could there be intelligent life on other planets? This question has piqued imagination and curiosity for decades. Explore the answer with the Drake Equation -- a mathematical formula that calculates the possibility of undiscovered life.
Billions of stars. Billions of galaxies. A thousand years just to count all of the stars in our galaxy and then another thousand to count the galaxies in the universe.

But why is this so important? Should we be spending less time searching for life when there are so many things we could be doing on Earth?
