A team of researchers led by Yasuhiro Oba, from Hokkaido University in Japan, has finally managed to find cytosine and thyminethe two missing nucleobases, in three known meteorites: those of Murray, Murchison and Tagish Lake.
For decades, astronomers have toyed with the idea of panspermia, the theory that life, or at least its essential elements, did not originate on Earth but came to our planet aboard meteorites. And although scientists have already found numerous organic compounds and molecules in these space rocks, so far they had only managed to identify three of the five primary nucleobases, namely adenine, guanine and uracil.
But no sign of the other two.
