Episode 176: Second Genesis, with Jay Melosh
Description
Feature Guest: Jay Melosh
If we should find creatures crawling around Titan or swimming under the ice sheets of Europa or Enceladus, they will almost certainly turn out to be the result of a second genesis, those creatures truly alien in the most profound sense. That startling conclusion follows from a series of groundbreaking simulation that found it exceedingly unlikely that life can be successfully transferred between the worlds of our solar system. To unpack the significance of this conclusion, today we’re joined here at The Star Spot by geophysicist Jay Melosh, who caused an uproar when he presented his findings at a recent meeting of the American Geophysical Union.
