On this episode of ID the Future, Bijan Nemati, formerly of CalTech’s Jet Propulsion Laboratory and now at the University of Alabama, Huntsville, tells what science is learning about how hard it is to find a planet like Earth. Anywhere. The more we learn about the conditions necessary for a planet to host life, the more we see we may need to search at least tens of thousands of Milky Way galaxies to expect to find another one — at least if it all depends on blind luck. This talk is part of bonus material included with the new, thought-provoking series Science Uprising.
On this episode of ID the Future, Discovery Institute Senior Fellow Jay Richards speaks with astrobiologist Guillermo Gonzalez about new research just reported in the Astrophysical Journal. The research suggests that the circumstellar habitable zone for terrestrial planets around stars is narrower than previously thought. This zone around stars, often referred to as the “goldilocks zone,” is where planets are not too hot and not too cold to support liquid water on the surface and, with it, complex life. But there’s another factor, previously underappreciated, which greatly curtails how much further a planet can be situated from its host star without running into trouble. It makes earth’s position that much more fine-tuned for life and, as Richards and Gonzalez discuss, Read More ›
