Re: Earth's cousin?
Worth investigating, to the extant we can, sure. At this point, not much to get excited about, and even should they be able to discern an atmosphere, let alone having oxygen and other gasses which could signal the possibility of life, that does little good here except as a point of philosophy. Folks here on Earth already have a hard time accepting basic tenants of biology, getting them to buy the set of conclusions (however logical and based on facts of how chemistry and biochemistry work) that lead to concluding life could exist on that planet is a tall order to say the least.
We are quicksilver, a fleeting shadow, a distant sound... our home has no boundaries beyond which we cannot pass. We live in music, in a flash of color... we live on the wind and in the sparkle of a star! Endora, Bewitched
