Wow! I've often wondered about life elsewhere in space. I found it a redundant argument to say life can't exist in extreme environments from our own. Well, human life can't, yes. Doesn't mean that other life doesn't exist. Hell look at the animals living in the ocean. We sure can't survive under all that pressure, but look at the organisms that can.
Really fascinating news, anything to do with space just grabs my attention. I'd even say that there is another Earth like planet out there with human like organisms of the same genetic material as us, if maybe perhaps slightly different. Would they be less advanced than we are? More so? Are they equally clueless about what lies out there in the universe? Argh, it blows my mind thinking about it.
