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 .
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 .
L-excesses from 3 – 15% in several non-protein α-dialkyl amino acids have been found in the Murchison and Murray meteorites. [25] Their extraterrestrial origin is indicated by their absence in biological systems and significant heavy isotope enrichments in 13 C and deuterium compared to terrestrial values. [ 26 ]
The meteorite was a type called a carbonaceous chondrite that is rich in carbon and also contains phosphorus. Its diameter was approximately 23-36 miles (37-58 km), Drabon said, making it about 50 ...
Cronin's research explored the organic chemistry of meteorites, with a specific focus on carbonaceous chondrites like the Murchison meteorite. His work provided valuable insights into the diversity and complexity of extraterrestrial organic compounds and their potential role in the origin of life on Earth.

By studying the composition of meteorites that have landed over the years and the asteroids populating our solar system, astronomers have determined that about 70% of known meteorite impacts came ...
The Murchison meteorite is on display at the Smithsonian's NMNH. The Murchison meteorite has been thoroughly studied; it fell in Australia close to the town that bears its name on 28 September 1969. It is a CM2 and it contains common amino acids such as glycine , alanine and glutamic acid as well as other less common ones such as isovaline and ...
