A large planetary body inferred from diamond inclusions in a ureilite meteorite

open access: yesNature Communications, 2018
Planetary formation models show that terrestrial planets are formed by the accretion of tens of Moon- to Mars-sized planetary embryos through energetic giant impacts. However, relics of these large proto-planets are yet to be found.

Search for Past Life on Mars: Possible Relic Biogenic Activity in Martian Meteorite ALH84001

open access: yesScience, 1996
Fresh fracture surfaces of the martian meteorite ALH84001 contain abundant polycyclic aromatic hydrocarbons (PAHs). These fresh fracture surfaces also display carbonate globules. Contamination studies suggest that the PAHs are indigenous to the meteorite.
