Amino Acids in Chondrites
Many theories about the origins of life involve the delivery of organic molecules to the early Earth by objects from space. Previously, scientists have identified amino acids in carbon-rich meteorites. […]

Organic Matter in the Enstatite Chondrite Sahara 97096 (EH3)
The insoluble organic matter (IOM) of an unequilibrated enstatite chondrite Sahara (SAH) 97096 has been investigated using a battery of analytical techniques. As the enstatite chondrites are thought to have […]

New Insight Into Solar System Transition Disk Phase by Unusual Meteorite Isheyevo
Many aspects of planet formation are controlled by the amount of gas remaining in the natal protoplanetary disk (PPDs). Infrared observations show that PPDs undergo a transition stage at several […]

Martian Meteorite Yields More Evidence of Possibility of Life on Mars
The finding of a ‘cell-like’ structure, which investigators now know once held water, came about as a result of collaboration between scientists in the UK and Greece. Their findings are […]

Vitamin B3 Might Have Been Made in Space, Delivered to Earth by Meteorites
Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the […]

Nature's Starships: Observed Abundances and Relative Frequencies of Amino Acids in Meteorites
The class of meteorites called carbonaceous chondrites are examples of material from the solar system which have been relatively unchanged from the time of their initial formation. These meteorites have […]
