So much wrong with this. Suffice it to say you have no idea what you're talking about.

Serious post:
Thanks SD, I wanted to point out how wrong this was but I've been spewing bullshite this whole thread so I didn't feel I was in a position to do so.

Looks like in October 2018 they're going to roll out this Telescope, and it will be able to detect the atmosphere of distant planets by the way the light from the home star refracts through the atmosphere. So, maybe in 5 years we'll know what the atmosphere is like on this little bitch we call Kepler 452-b.
Nevermind, Kepler 452-b will be too far away for the Webb Telescope to read its atmosphere.

The fact that they can do science wizardry shite like this just blows my mind. So awesome.

Not wizardry. Spectrometry For example, if you were to view hydrogen under a spectrometer you would see that it has some absorption/emission lines like this:
Now, this can be seen on earth in a lab OR out in space when examining stars. If we were to take the light from a star and see this spectrum we can safely conclude it is made of Hydrogen.
That's all, not magic.

I hope I live to see a telescope that can see the spectrum of a planet ~1500ly away. It would be really frickin cool to confirm an earth-like planet with a hospitable atmosphere for man.

It is more likely to naturally become uninhabitable prior to the earth.

no not quite right
the photon curve is associated with the wobble of the star to estimate the size of the planet because the wobble will have a periodicity.
it could be a slow moving small planet that dips the photon curve just as much a fast moving large planet yet their wobble effects on the center of mass of the system will be totally different.
I would also add that Im pretty sure this instruments used to detect the dip in the photon curve are so sensitive that its probably able to estimate the size of the planet on that component alone.
