Comet Landing 2014: Rosetta Probe Philae Discovers Organic Molecules: Report
http://www.ibtimes.com/comet-landing-2014-rosetta-probe-philae-discovers-organic-molecules-report-1725228
“The Philae space probe was powered down earlier than expected, but not before an instrument discovered an organic compound that was first detected in the comet’s atmosphere, the Wall Street Journal exclusively reported Monday. The find is extraordinary considering the organic compound contains the carbon atom, which is the basis of life on planet Earth.”

“How life originated on earth is a question that people have pondered for ages. Theories abound, from those based on religious doctrine, to the purely scientific, to others that border on science fiction. One possibility that hovers on this border is the panspermia theory, which suggests that life on Earth did not originate on our planet, but was transported here from somewhere else in the universe.”

‘Necropanspermia’ Suggested As A Way Of Seeding Life On Earth
http://phys.org/news/2010-11-necropanspermia-seeding-life-earth.html
“Panspermia is a mechanism for spreading organic material throughout the galaxy, but the destructive effects of cosmic rays and ultraviolet light tend to mean most organisms would be destroyed or arrive on a new world broken and dead. Now Paul S. Wesson, a visiting researcher at the Herzberg Institute of Astrophysics in Canada, suggests the information contained within damaged organic material could seed new life. He terms this process necropanspermia.”
