NASA Spots 1st Molecule of the Universe
▪️The scientists have detected the 1st molecule to ever form from stray atoms in the universe. The 1st such molecule was helium hydride, a combination of helium and hydrogen.
▪️The discovery is a 1st step in unlocking the mystery of the universe’s chemistry. About the Discovery The research was published in the journal Nature.
▪️The researchers used the National Aeronautics and Space Administration’s (NASA’s) SOFIA, the world’s largest airborne observatory, to detect helium hydride in NGC 7027, a planetary nebula about 3,000 light-years away from Earth.
▪️SOFIA Stratospheric Observatory for Infrared Astronomy (SOFIA) is a Boeing 747SP jetliner modified to carry a 106-inch diameter telescope.
▪️Scientists for long had held that around 100,000 years after the big bang, helium and hydrogen combined to make a molecule called helium hydride for the rst time. But scientists could not nd HeH + in space and it was unproven.
▪️The discovery brought a long search to a happy ending and eliminates doubts about our understanding of the underlying chemistry of the early universe.
