Astronomers find oldest type of molecule in space
Everything has a beginning. That’s true for stories, for people, for the universe and even for chemistry. The Big Bang itself produced just a handful of elements (variations of hydrogen, helium and lithium nuclei), so researchers have a pretty good sense of what the first atoms and molecules might have been. But the very first molecular bond to form, linking together atoms of different elements in a single molecule, has long been missing in action.
