 With a little trip to space and beyond and look for evidence of intelligence among the stars, my guest is author, astrobiological researcher, and retired Army Major David Toon. With an honored 22-year career in military intelligence and aviation, he now goes by the name of David. His book is called Solar Suspicions. He's known as the techno-signature hunter. He has a personal collection of 60,000 images found in NASA's Solar Satellite Archive.
