  Is there other intelligent life in the universe, or are we all alone? Now you can explore this question through 17 compelling conversations with leading experts on extraterrestrial life.  The prospect of alien intelligences has long captivated cosmologists, perplexed theologians, and provided rich fodder for science fiction writers. While we may doubt that the large-eyed, green-skinned figures of sci-fi films will one day descend to Earth in UFOs, it is far harder to reject wholesale the possibility that intelligent life—in some form yet unknown—exists.  Alongside host Robert Lawrence Kuhn of Closer to Truth (PBS), you’ll discover that whether or not we’re alone is but one of a myriad of questions raised by the possibility of other intelligent life forms.  Kuhn’s guest experts—among them renowned astrophysicists, computer scientists, and philosophers—explore various facets of alien life through key inquiries such as the following:If the probability that other intelligent life exists is so high, why is there no evidence of it?What effect would discovering other forms of life have on our culture and belief systems?If we are indeed alone, does that mean we’re destined to colonize the universe? Taking you on a mind-bending journey through theories and galaxies, this audio series illuminates the profound implications of finding out if we are the universe’s sole travelers. This course is part of the Learn25 Collection.

  Destination Mars - The Story of...

  When the Apollo astronauts walked on the Moon in 1969, many people imagined Mars would be next. However, NASA’s Viking 1, which landed in 1976, was just a robot, and the much-anticipated crewed mission failed to materialize, defeated by a combination of technological and political challenges. Four decades after Viking and almost half a century after Apollo, technology has improved beyond recognition—as has politics. As private ventures like SpaceX seize center stage from NASA, Mars has undergone a seismic shift—it’s become the prime destination for future human expansion and colonization. But what’s it really like on Mars, and why should anyone want to go there? How do you get there, and what are the risks? Astrophysicist and science writer Andrew May answers these questions and more, as he traces the history of our fascination with the Red Planet.

  An urgent plea for a broader understanding and awareness of the unconsidered dangers of new genetic technologies 
   
   
   
  Since 2010 it has been possible to determine a person's genetic makeup in a matter of days at an accessible cost for many millions of people. Along with this technological breakthrough there has emerged a movement to use this information to help prospective parents "eliminate preventable genetic disease." As the prospect of systematically excluding the appearance of unwanted mutations in our children comes within reach, David B. Goldstein examines the possible consequences from these types of choices. 
   
   
    
  Engaging and accessible, this clarion call for responsible and informed stewardship of the human genome provides an overview of what we do and do not know about human genetics and looks at some of the complex, yet largely unexplored, issues we must be most careful about as we move into an era of increasing numbers of parents exercising direct control over the genomes of their children.
