Really? This is the first time I'm hearing that. I've seen "planet discovered" a bunch of times, with a crescendo of excitement. I was always disappointed that they were almost exclusively super-giants and the "so what" line always said something like "and if this super-giant has moons, they could be habitable!"

This is the first time I've seen a story about an actual earth-like (with fairly loose parameters) planet that is roughly in the life-zone! Usually headlines that say "earth-like planet discovered!" involve either a frozen rock orbiting way outside of its sun, or a burning pebble right next to it.

However important this particular planet is, I think it's a first as far as fairly plausible life candidates go. Here's to more!
