    Great they found a planet that once might've had life on it but now it's broken apart LOL

      Scientists use the term "Earth like" a little too broadly, I think. If the atmospheric pressure is 50 times Earth's, is it Earth like? If the gravity is 30 times more than Earth, is it Earth Like? If there isn't an atmosphere, is it Earth Like? If there is no spinning Iron core, and thus no magnetic field to shield out deadly radiation...is it Earth Like?

      Scientists can basically see the ratio of different elements, and estimate the size of the planet...the speed of it's orbit.

      Eventually, we may be able to detect vegetation, and that would be a good sign. And then hope it takes less than a million years to get there.

      What if they're not stars? What if they are holes poked in the top of a container so we can breath?

    What I worry about when they say "earth-like" is does that mean the water has sodium fluoride dumped into it, the general ecosystems poisoned into desertification, and radiation from nuclear melt down circling their globe?

      Yes, that's why it ended up like that

        Hmmm, in all honesty it can't be Earth like, if it was then Genetically modified Frankenstein crops would be scouring the planet and making a large number of the insects die out due to eating this stuff.

        here are some interpretations of possible plant life after the alien scientists mucked around with it!

          I would think that if a planet is really "Earth like" that there would be life on it, probably single cell (Like most of Earth history).

          If there were a way to detect bio-mass, from these distances, it would give us a good idea if the planet was suitable for us.
