The midday news over here carried a report about it. I assume it's somewhat of a big deal here becasue I live in Switzerland and Swiss scientists helped make the discovery. They're toting it as "Swiss astronomers make a critical breakthrough in answering one of mankind's biggest questions" or something along those lines

The news report mentioned the planet being 20 light years or so away and it's all nice thinking about exploring said planet etc etc. but how the heck do they expect to do it within any forseeable time? What would be a reasonable timeframe to expect space travel of that scale anyway? 500 years or more?
