NASA Discovers Life's Building Block In Comet
xp65 writes "NASA scientists have discovered glycine, a fundamental building block of life, in samples of comet Wild 2 returned by NASA's Stardust spacecraft. 'Glycine is an amino acid used by living organisms to make proteins, and this is the first time an amino acid has been found in a comet,' said Jamie Elsila of NASA's Goddard Space Flight Center in Greenbelt, Md. 'Our discovery supports the theory that some of life's ingredients formed in space and were delivered to Earth long ago by meteorite and comet impacts.'"
No, all it means is that some of the chemicals needed for Earthly life are also found in elsewhere in the Solar System. Given that the entire Solar System formed out of the same molecular cloud that is not very surprising.
Just because you are paranoid does not mean that no-one is out to get you.
This comet orbits the Sun every 6.39 years.
The chemicals on it might just as well have been knocked off from Earth to begin with as coming from elsewhere in the Solar System.
