Ryugu e le sue cicatrici da bombardamento cosmico
#asteroidi #Ryugu @[email protected] @[email protected]
Un team di ricercatori ha scoperto che l'asteroide Ryugu è stato oggetto, negli ultimi mille anni, d’un intenso bombardamento di micrometeoroidi. La prova è uno strato di sodio ultrasottile – meno di dieci nanometri – trovato sulla superficie dei campioni raccolti dalla missione Hayabusa 2

Spannend, die Bausteine des Lebens scheinen in vielen Meteoriten vorzukommen, wie jetzt eine Untersuchung an Proben von #Bennu, #Ryugu und zwei auf der Erde gefundenen Meteoriten nachgewiesen wurde.

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.

"n a study published in Nature Astronomy today, a team of Japanese scientists has confirmed all five nucleobases are present in this pristine asteroid [Ryugu] material.
This means these ingredients for life may have been widespread throughout the Solar System in its early years."

[SummerNews #5 ] For the first time, large-scale #PAHs (polycyclic aromatic hydrocarbons) (> 50 #carbon atoms) have been discovered in a carbonaceous #asteroid sample: #Ryugu 👍 👏
Brought back by the #Hayabusa2 mission from JAXA, this sample was the subject of a unique #surface mass spectrometry technique based on two-stage #laser desorption/ionization, available on the #AROMA device at IRAP.

Studies of samples of asteroid Ryugu returned by the Hayabusa-2 mission show that the action of water and organic material on carbonaceous asteroids lead to the widespread occurrence of micron-sized #polymeric organic particles encapsulating clays and biological relevant #molecules.

"Here we report the detection of uracil, one of the four nucleobases in ribonucleic acid, in aqueous extracts from Ryugu samples. In addition, nicotinic acid (niacin, a B3 vitamer), its derivatives, and imidazoles were detected in search for nitrogen heterocyclic molecules."This is an important step in detecting life and also it's origins in the universe.

Samples of #asteroid #Ryugu collected by #Hayabusa2 had #uracil, one of the informational units that make up #RNA, the molecules that contain the instructions for how to build and operate living organisms. Vitamin #B3 or #niacin, which is an important cofactor for #metabolism in living organisms, was also detected in the same samples
