How’s Life on 67P?–Philae Found Organic Material on Comet

This might confirm the theory that life on Earth came from the outer space.

Although scientists still analyze data gathered by space probe Philae, which successfully landed on a distant comet on November 12th, after 10-year journey on its carrier Rosetta, first data are showing presence of organic, carbon-based substances. Presence of the water in the mixture of ice and dust was also confirmed. For now, this discovery supports the theory that the life on Earth was probably transplanted by asteroids and comets that contained some primitive forms of life.

European Space Agency (ESA) reported that, before its batteries were exhausted, lander Philae, through its specialized instrument COSAC, one of 20 lander’s sophisticated devices ‘smelled’ the atmosphere and detected some organic molecules. Spectrum analysis and identification of molecules continues – was reported by the German Aerospace Center (DLR). Although scientists have yet to work out what kind of molecules were actually present on the comet, the discovery of organic substances could lead to new comprehensive knowledge about origins of life on Earth, that’s always been one of the one of the greatest Rosetta_and_philaemysteries of the mankind.

Primordial soup
In his famous experiment conducted in 1953, American scientist Stanley Miller showed that basic chemical building blocks for life, such as amino-acids, could have resulted from conditions present on Earth some 3.8 billion years ago. That experiment gave birth to the theory of ‘primordial soup’ in which life was born. During the 1970s, however, scientists Fred Hoyle and Chandra Wickramasinghe launched the theory known as ‘panspermia’. According to this theory, life on Earth was transplanted from space by asteroids and comets carrying primitive life forms. Hoyle once humorously remarked that the probability of life on Earth ‘springing’ by itself is as likely as that the material left on the dump with the help of strong tornadoes, could assemble a Boeing 747.

Nevertheless, these theories are still prevalent scientific explanations of the origins of life on Earth. Thanks to spectroscopy, we know that universe contains organic molecules. Did the material from the outer space contribute to the birth of first living organisms on Earth is still open to debate. Perhaps some questions are best left unanswered.
