New paper indicates potential for primitive life on icy Barnard b super-earth planet if geothermal activity exists

Barnard b (or GJ 699 b) is a recently discovered Super-Earth planet orbiting Barnard’s Star, making it the second nearest star system to the Earth. Although likely cold (-170 degrees centigrade), it could still have the potential to harbor primitive life if it has a large, hot iron/nickel core and enhanced geothermal activity. That was a conclusion announced by Villanova University Astrophysicists Edward Guinan and Scott Engle at a January 10 press conference held at the 233rd meeting of the American Astronomy Society (AAS) in Seattle, WA.
