# chem: HeH+, the beginning of chemistry

In the planetary nebula  NGC 7027 <<  SOFIA (Stratospheric Observatory for Infrared Astronomy) detected helium hydride, a combination of helium (..) and hydrogen (..), which was the first type of molecule to ever form in the early universe. This is the first time helium hydride has been found in the modern universe. >>

<< It was the beginning of chemistry, >> David Neufeld.
