I'm thinking about all of the crazy things we've discovered such as the planet with burning ice (Gliese 436-B), the zombie planets constructed from the remains of planets blown up from the explosion of their star, the planet with a ring system 200 times larger than Saturn's (J1407-B), the planet so hot that it condenses metal into clouds (Wasp 121B).

See this video for further explanation on these planets. :)

Jupiter seems to be pretty unique with all it has going on in the different 'latitudinal layers', and I think Neptune or Uranus also rains gemstones or something, doesn't it? Would astronomers of another civilization (assuming they can "see" these planets since they're relatively small compared to most of the planets we're finding at the moment) be wowed by any of our planets? Again, other than Earth because of the implications of life.

Also, are there other features of our solar neighborhood that would be interesting? Such as the asteroid belt?
