Extra-solar planets is indeed the coolest thing going on.

I was awakened to it about 4 years ago when the 20 some-odd known at the time were featured in Discover Magazine which I saw in a Dr.s office.
I photo-copied the three pages depicting the planets which I still have, somewhere.

I keep hoping we find planets around the very closest stars, such as Alpha Centauri, or Barnard's Star.
