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

Professor Chandra Wickramasinghe and colleagues at the University's
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. From where can I get the original paper?
