First Organic Molecules Found on Alien World 146
Galactic_grub writes "The detection of planet HD 189733b is in some ways just another small victory for extra-solar planetary science. It is too hot for there to be anything 'alive'. Just the same, somewhere on the planet are trace amounts of the gas methane. The fact that the element was detected at all offers hope for understanding future discoveries of Earth-like worlds, says NewScientistSpace. Researchers from Caltech and University College London used the Hubble Space Telescope to peer at the planet and examined spectral signature of starlight filtered by the planet's atmosphere, to identify different chemicals. 'The authors suggest that some ill-understood chemical process might be responsible, either concentrating the methane in cooler parts of the atmosphere, or generating extra methane directly. Alternatively, the methane might simply mean that the planet happens to be very rich in carbon.'"

That group of compounds (things like methane, ethane, propane, butane etc.) are all part of organic chemistry, and whether you find them with or without life they are still organic chemistry.

Now, mind you, even if we have to abandon dreams of Silicate life in extrem hot environment, it does not mean we think life could be identical to what we have on earth.
