This article probably could make more effort than it does to point out that that isn't a real photo and that while travelling at light speed would get you there in 20 years, our technology isn't nearly that fast.
Definitely a cool find... they just probably want to draw more attention to the real timescales involved. If we launched it today, in significantly more than 20 years, we could land a transmitter on this planet, and 20 years after its landing, we'd start receiving its broadcast. Barring some major breakthroughs in space travel and/or longevity, our generation probably won't see anything from this discovery.
Of course that just means we should all start researching faster (even FTL) travel, medical science so we can live long enough to see the results, and/or more powerful telescopes so we can at least see it from here.
