Organic #molecules delivered from #extraterrestrial materials may have played a key role in supplying building blocks for #life on #Earth.

Now scientists report all five canonical #nucleobases—purines (#adenine and #guanine) and pyrimidines (#cytosine, #thymine and #uracil)—in samples returned from the C-type #asteroid (162173) #Ryugu.

Samples from Ryugu, #Bennu and #Orgueil, which have a similar mineralogy and elemental composition, show purine-to-pyrimidine ratios negatively correlating with #ammonia.

These observations indicate that the nucleobases in these samples may have formed via a shared pathway depending on the physicochemical environment of the respective parent bodies.

The detection of diverse nucleobases in asteroid and meteorite materials demonstrates their widespread presence throughout the Solar System and reinforces the hypothesis that carbonaceous asteroids contributed to the #prebiotic chemical inventory of early Earth.

Asteroid Bennu’s Rugged Surface Baffled NASA, We Finally Know Why https://science.nasa.gov/missions/osiris-rex/asteroid-bennus-rugged-surface-baffled-nasa-we-finally-know-why/ #NASA #Asteroids #Astromaterials #Bennu #GoddardSpaceFlightCenter #JohnsonSpaceCenter #OSIRISRExOriginsSpectralInterpretationResourceIdentificationSecurityRegolithExplorer #PlanetaryScience #PlanetaryScienceDivision

"The #asteroid #Bennu continues to provide new clues to scientists’ biggest questions about the formation of the early solar system and the origins of life. As part of the ongoing study of pristine samples delivered to Earth by NASA’s #OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) spacecraft, three new papers published Tuesday by the journals Nature #Geosciences and Nature #Astronomy present remarkable discoveries: sugars essential for biology, a gum-like substance not seen before in astromaterials, and an unexpectedly high abundance of dust produced by supernova explosions."

Finally here! Two years after #NASA 's #OSIRIS-REx mission returned samples of #asteroid #Bennu to Earth, we have now received 319 mg to study in our labs. We are hoping to determine Bennu’s isotopic composition and learn more about its “birthplace” in the Solar System.
