Astronomers are reporting today the discovery of a planetary system way out of tilt, where the orbits of two planets are at a steep angle to each other.
NASA's Spitzer Space Telescope has made the first measurements of the day and night temperatures of a planet outside our solar system. The planet circling very close to its sun is always as hot as fire on one side, and potentially as cold as ice on the other.
Except for the fact that we call it home, for centuries astronomers didn't have any particular reason to believe that our solar system was anything special in the universe. But, beginning with the discovery 10 years ago of the first planet outside our solar system, evidence suggests that, as far as planetary systems go, the solar system might be special indeed.
