Murchison Meteorite for Sale - New
The Murchison meteorite is a carbonaceous chondrite. This meteorite fell to Earth on September 28, 1969, scattering fragments across pastures near Murchison, Victoria, Australia.
Most amino acids can exist in either a right-handed or left-handed form. In biology, however, only the left-handed forms are used. The original reason for this anomaly is not known. If life originates from nonliving chemicals there is no convincing reason for one form to be selected and not the other. Amino acids produced non-biologically would have no obvious reason to accumulate excesses of either form. Scientists have found measurably more left-handed than right-handed versions of certain amino acids in the Murchison meteorite.
Although astronomical processes have been hypothesized, no non-biological process is known to produce this asymmetry. Instead, the case for life forms or life's chemistry in meteorites has always been open to the suggestion that meteorites are easily contaminated with biological products after reaching Earth. Scientific study of the Murchison meteorite has discovered that the amino acids in the meteorite was is not the result of earthly contamination.
The relationship between these amino acids and Earthly life is exactly why we're all interested in this meteorite and makes it an important specimen to have in teaching or part of a meteorite collection. Lab results on this meteorite increase the weight of the previous argument for panspermia based on biological amino acids from Murchison.
