I think this research is really exciting there is a distinct possibility we may find evidence of life elsewhere in my lifetime. On a side note, what's interesting is the confidence scientists seem to express that life will be found. They seem to assume if an exoplanet is in the 'Goldilocks' zone with earth like conditions it should result in life occurring. Is that thinking justified considering we don't actually know how life processes began?
“That doesn’t prove they're definitely capable of supporting of life,” he said. After all, one or two of the three planets could be like Venus in our solar system, which has nasty conditions. But still, three planets is better than two or one, odds-wise. “With three bites at the cherry, you have to be optimistic that there’s a good shot one of them has the potential to be Earth-like.”
He added: “As far as we know right now, I’d say there are no show-stoppers to stop life from living on these worlds.”
