Did life begin in space?

Recent probes inside comets show it is overwhelmingly likely that life began in space, according to a new research paper by Cardiff scientists.

Professor Chandra Wickramasinghe and colleagues at the Cardiff Centre for Astrobiology have long argued the case for panspermia – the theory that life began inside comets and then spread to habitable planets across the galaxy. A recent BBC Horizon documentary traced the development of the theory.

Now the team claims that findings from space probes sent to investigate passing comets reveal how the first organisms could have started.
