Scientists find a chemical "missing link"

Astronomers using instruments to detect radio signals emitted by atoms were able to detect Helium hydride, a molecule believe to have formed about one hundred thousand years after the "Big Bang".  

Long suspected but never found until now, this molecule is believed to be the link between the universe of energy and the universe of matter we live in today.
