Astronomers have revealed that they've found for the forst time a so-called "Goldilocks Planet", one which orbits its sun at a distance not too far, not too close, but just right for life as we know it to possibly develop.  Tagged as Gliese 581g, it orbits its sun at a distance of about 14 million miles and makes that trip in 37 days.  It has an atmosphere, but further checks needs to be done with spectrographs to determine the composition of that atmosphere.  It's roughly 20 light years away, and although that seems far, in the vastness of the universe, this is a walk in the park.  Maybe this is where some of those ETs are coming from.
