Â Â Â The Rosetta spacecraft has discovered all the elements of life in the gases jetting from a comet as it approaches the Sun.
The ingredients that make up amino acids, lifeâs building blocks, are all contained in the tail of the comet 67P/Churyumov-Gerasimenko (67P/C-G). Among them are methane, methanol, CO2, ammonia and water. All proteins are made of amino acids.
If Rosettaâs lander, Philae, discovers complete amino acids when it reaches the cometâs surface in November, it would support the hypothesis that life on Earth was seeded by comets with complex organic molecules as well as water. . . .
