"The 2005 Deep Impact mission to Comet Tempel 1 discovered a mixture of organic and clay particles inside the comet. One theory for the origins of life proposes that clay particles acted as a catalyst, converting simple organic molecules into more complex structures. The 2004 Stardust Mission to Comet Wild 2 found a range of complex hydrocarbon molecules - potential building blocks for life.

Professor Wickramasinghe said: “The findings of the comet missions, which surprised many, strengthen the argument for panspermia. We now have a mechanism for how it could have happened. All the necessary elements - clay, organic molecules and water - are there. The longer time scale and the greater mass of comets make it overwhelmingly more likely that life began in space than on earth.”
Regardless of what we think, whether it's "sloppy journalism, bad science," unsurprising by association, or doubtful for lack of more evidence, the paper appears to have been accepted for publication in a peer reviewed journal.
Which begs the question: If such skeptical reviews were of any weight, is the international peer review process flawed?
