This feels like the start of a sci-fi movie.  And to be fair, we're not really seeing it, we're seeing a dimming of the star in the sky, and from that there's a bunch of math involved that lets us figure out how big the planet is, how far it is from the sun, how fast it's moving, etc.  The important thing, water, we probably have NO clue about that (if we did, they'd have said).  it is kind of amazing to consider the idea that only 1400 light years away from us might be another world like ours.
