For years, we've believed that around 2 billion planets in the galaxy are able to support alien life. But what if we were wrong? Anthony discusses how new knowledge of the Goldilocks Zone could mean the possibility of life on up to 60 billion planets! 

 

1. What is the ¡®goldilocks zone¡¯?

2. Do you agree that it¡¯s possible that billions of planets in the Universe can actually harbor life? 

3. Do you think we can discover more planets that are habitable? Do you believe aliens exist?
