The Murchison meteorite is a meteorite that fell in Australia in 1969 near Murchison, Victoria. It belongs to the carbonaceous chondrite class, a group of meteorites rich in organic compounds . Due to its mass (over 100 kg or 220 lb) and the fact that it was an observed fall , the Murchison meteorite is one of the most studied of all meteorites .
Shortly after its fall and recovery in Australia in 1969, the Murchison meteorite was found to host five protein amino acids (glycine, alanine, valine, proline, and glutamic acid) in addition to 12 non-proteinogenic amino acids including α-aminoisobutyric acid and isovaline, which are rare on Earth.

Presolar grains of the Murchison meteorite. In the 1960s, the noble gases neon [5] and xenon [6] were discovered to have unusual isotopic ratios in primitive meteorites; their origin and the type of matter that contained them was a mystery.

CM chondrites are a group of chondritic meteorites which resemble their type specimen, the Mighei meteorite. The CM is the most commonly recovered group of the ' carbonaceous chondrite ' class of meteorites, though all are rarer in collections than ordinary chondrites .
[67] [68] [69] The Murchison meteorite that fell near Murchison, Victoria, Australia in 1969 was found to contain an amino acid distribution remarkably similar to Miller-Urey discharge products.
