Michael Wall joins the program. Wall is a senior writer for Space.com. He has just written OUT THERE...A Scientific Guide to Alien Life, Antimatter and Human Space Travel (for the cosmically curious).
Wall explores the myriad of questions that would arise once we do discover life beyond Earth. Like: what would the first aliens we meet look life? Little green men or microbes? It's part science, part humor, and it's already a bestseller.
