Another Planet Found That Can Sustain Life?

Scientists have discovered another "earth" (earth, jr.), similar to our own 20 light years away.  According to Discovery, it might be habitable and in fact, could already have life on it!  Read about it here.  There are some differences (in terms of day/light and temperature changes), but the opinion seems to be that it can sustain life.

How cool.  I've always thought we'd have to be pretty close-minded to think we are the only ones out there. 

There is also talk that Christians will not like this discovery.  I don't know about that, not being Christian myself any longer, but I think it's pretty cool to know it exists, instead of just think it does.
