Another planet found that can support life?

Example: If I tell you there is a suitcase in a cave with a million bucks in it, and all you have to do is go get it. But upon entering you find a bear with her cubs. And as the mother bear mauls you, you holler out why did you not tell me? I holler back: It was not important. But it was wasn’t it? Same thing here. They want you to make the step towards believing that life exists on other planets, and probably exists on the one they found. But leave out what is required for life to exist which goes way beyond a planet just being in the goldilocks zone.


If you watch the video above, you would have heard that NASA believes they have found another planet to support life. My question is: They can barely see the planet Pluto, how do they see this one enough to make this claim?
