Very interesting indeed.
Along with Amino Acids forming in the interstellar medium we can now add nucleobases.
I would offer caution, however, and not bow to the hyperbole the BBC seemed to be displaying.
We’ve known for some time that organic molecules can spontaneously form and come to us from space. The addition of nucleobases to the list is interesting. It does not show strong evidence, however, of “extraterrestrial origins of life,” but of extraterrestrial origins of lifeless molecules. This lends nothing to the panspermia overtones in the BBC piece.
I especially liked the “how did they get into the (meteor) in the first place” question posed at the end of the piece.
