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 .
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.
The group takes its name from Mighei (Ukraine), but the most famous member is the extensively studied Murchison meteorite. Many falls of this type have been observed and CM chondrites are known to contain a rich mix of complex organic compounds such as amino-acids and purine/pyrimidine nucleobases. [11] [12] [13] CM chondrite famous falls ...

Isovaline is a rare amino acid transported to Earth by the Murchison meteorite [citation needed], which landed in Australia in 1969. The discovery of isovaline in the biosphere demonstrates an extraterrestrial origin of amino acids and has been linked to the homochirality of life on Earth, [1] suggesting a role in the origin of life.
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.
