Why all the fuss? (Score 1)

I really cannot understand why people are so surprised by the idea of "extraterrestrial" (I cannot think of a better adjective) planets. If there are 9 planets around our sun, it seems very likely that other solar systems also have planets. Other planets have also been detected through indirect measurments, yet the excitment of these as worn off. This new "direct" discovery has refreshed people's imaginations, which I feel is a good thing, yet I cannot figure out why... Just my 2 bits
