"NASA Researchers Make First Discovery of Life's Building Block in Comet." From Bill Steigerwald, NASA Goddard Space Flight Center
August 17, 2009
"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 Dr. 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."
Q. A.: To social anthropologists: will people of Faith
a) begin to accept the evidence of science and evolution and gradually abandon the notion of creationism
b) accept the scientific facts but adjust their belief systems to accommodate them
c) allow religious fundamentalists to attack science as misinformation (again) and allow their religious leaders to prohibit rational, scientific debate?
What's your guess?
Q. B.: What other precursors of living molecules would you expect to be discovered in space debris next? Presumably they must be able to survive:
a) extremes of temperature
b) a broad range of radiation
c) prolonged absence of liquid water
Care to hazard a guess?
