Murchison meteorite
"[3] On 28 September 1969 at approximately 10:58 a.m. local time, near Murchison, Victoria, in Australia, a bright fireball was observed to separate into three fragments before disappearing,[1] leaving a cloud of smoke.Like most CM chondrites, Murchison is petrologic type 2, which means that it experienced extensive alteration by water-rich fluids on its parent body[5] before falling to Earth.Around the same time, an enrichment in the isotope 15N was reported,[14] however this result and the non-racemicity of alanine (but not of the others) were explained as possibly due to analysis error.[19][20] The limited scope of the analysis by mass spectrometry provides for a potential 50,000 or more unique molecular compositions, with the team estimating the possibility of millions of distinct organic compounds in the meteorite.This specimen demonstrates that many organic compounds could have been delivered by early Solar System bodies and may have played a key role in life's origin.
