If there is life there they may have discovered us many years ago.
We are not necessarily the most advanced life from in the Universe.
Having had a chance to study us, and now having been "discovered", they may well decide that they don't want us poking around their solar system (and who can blame them?) and at this very moment their fleets are on their way to destroy us.
It's somewhere to point more telescopes and get more information on how this planet (and probably many other like it) formed. I, for one, thought this was very interesting news. It's relatively close proximity to earth makes the prospect of finding other rocky, inhabitable (or dare i say inhabited?) planets all the more likely.
