Alien Planet's Missing Methane Stumps Scientists

Alien Planet Has Pretty Weird Atmosphere
NASA's Spitzer Space Telescope has found evidence that a hot, Neptune-sized planet orbiting a star beyond our sun lacks methane -- an ingredient common to many planets in our own solar system. The planet illustrated here, called GJ 436b is about 980 degrees Fahrenheit (527 degrees Celsius) – it was expected to have methane but Spitzer's observations showed it does not.
