Not breaking news but a bit groundbreaking: in Nature Astronomy:
Koga, T. Oba, Y. Takano, Y. et al. A complete set of canonical nucleobases in the carbonaceous asteroid (162173) Ryugu s41550-026-02791-z
The big news is the discovery of all five “letters” of DNA/RNA in Ryugu samples from Hayabusa2. Previously, only “U” (uracil) had been reported; the other four were found in carbonaceous chondrite meteorites, and the Bennu sample from OSIRIS-REx. But meteorites are in contact with Earth’s biosphere; Bennu and Ryugu samples were collected and transported in controlled conditions. Ryugu, then, is important because the capsule seal of Haya2 is more trustworthy than the OREx capsule, and Ryugu is a more common type of asteroid (Cb) than Bennu (type B). The announcement of the remaining four nucleobases in Ryugu assures that the stuff of life is, yes, common in space.
