Investigating organic matter from asteroids to comprehend how and where the building blocks for life formed<\/strong><\/p>\n

Organic matter found in volatile-rich asteroidal materials is made of the elements C, H, O, N and S, which are thought to be important building blocks for life. Characterising the origin(s) of these organics thus constitutes a key step to constrain the origin of life on Earth, and appraise the habitability potential of other worlds in the Universe. Yet how and where these organics formed is still highly debated. To tackle this issue, researchers from The University of Manchester and collaborators in France used secondary ion mass spectrometry to precisely measure the oxygen isotope composition of refractory organics from two types of carbonaceous chondrites. Their results suggest that the bulk of carbonaceous chondrite organics formed in the nascent Solar System, possibly through chemical reactions occurring in the disk surrounding the young Sun, rather than in response to low temperature fluid circulations on asteroidal bodies. These findings suggest that if organic materials can form through simple chemical processes operating in our Solar System, it is likely that they are widespread in other planetary systems.<\/p>\n
