"Building blocks of life can originate in space."
"The idea isn’t that these building blocks are just passengers aboard meteorites, but that the chemistry inside asteroids and comets can actually manufacture the essential building blocks of biology. And a liquid chromatography and mass spectrometry analysis of sample meteorites and the environments where they were found seems to confirm this.
"This is big news, of course, because if the ingredients for life were brought here from some external source, there’s always the possibility that the same thing has happened elsewhere in the universe--possibly many times over."
(I wonder if other civilizations that took root elsewhere in the universe have produced anything as divine as Joni Mitchell.)
