Over the last week I've been following the reports offered by teams of scientists from NASA and universities in the US that have confirmed the presence of methane on Mars. Creationists' pucker factors currently stand at 9.37 out of 10.
Methane is an organic compound produced through geologic or biologic activity. Scientists have long suspected the presence of methane on Mars but haven't been able to confirm their suspicions until 2003. Astronomers at the Mauna Observatory turned the Keck Telescope toward our nearest neighhbor, while NASA used infrared scopes. They were able to detect three spectral absorption lines indicating that the Martian atmosphere does indeed contain methane. I'm not ready to say just that there is/was life on Mars just yet, but the idea is tantalizing.
