Pluto, a (dwarf) planet that is alive, vibrant and waiting to be understood

Pluto has long been misunderstood. In 2006 it was declared 'not a planet.' A decision planetary scientist Dr. Alan Stern calls B.S. (bad science).

Pluto is 3 billion miles away from earth and roughly the size of the United States. Scientist used to think it was dead, inactive and covered in crators. Until 2015, when the New Horizons spacecraft finally fufilled a mission two decades in the making. Dr. Alan Stern and Dr. David Grinspoon tell Bill Radke about the 'epic first mission to Pluto' as documented in their new book "Chasing New Horizons." courtsey
