Why in News?
- The scientists of NASA have detected the first molecule which is Helium Hydride that was formed from stray atoms in the Universe
- NASA Scientists Detect First Molecule of Universe – Helium Hydride is a combination of helium and Hydrogen
- The research was published in the journal ‘Nature’.
- The researchers used the National Aeronautics and Space Administrations 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.
What is SOFIA?
- Stratospheric Observatory for Infrared Astronomy (SOFIA) is a Boeing 747SP jetliner modified to carry a 106-inch diameter telescope
Significance of this discovery:
- 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 first time
- But scientists could not find 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
