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 .
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 ...
Analysis of the organic fraction of the Murchison meteorite with Fourier-transform ion cyclotron resonance mass spectrometry detected over 10,000 unique compounds, [70] albeit at very low (ppb–ppm) concentrations. [71] [72] In this way, the organic composition of the Murchison meteorite is seen as evidence of Miller-Urey synthesis outside Earth.
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 ...
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 ...
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 .

His work at the ASU Center for Meteorite Studies, particularly with carbonaceous chondrite meteorites, positioned him as a leading figure in the field. [citation needed] Cronin's research explored the organic chemistry of meteorites, with a specific focus on carbonaceous chondrites like the Murchison meteorite. His work provided valuable ...
