HN user avar posted a link to Phil Plait's writeup in this thread: http://news.ycombinator.com/item?id=1741330. Then HN user hartror suggested, "His write up is far more suitable for the HN audience, has plenty of science, grains of salt and uses the very scientific word 'probably' a lot (that isn't a joke)." So I figured it would be worth submitting. It seems to be a more levelheaded commentary on the discovery.
Apart from the obvious fact that this is a very cool finding, I have to say I love the term "Goldilocks zone". I wonder if we can misappropriate it for other uses.
