TEHRAN, Apr 20 - One of the first molecules to form after the Big Bang was spotted roughly 3,000 light-years from Earth in a dusty remnant of a sun-like star.
TEHRAN, Young Journalists Club (YJC) - The molecule was spotted by NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) in a planetary nebula, NGC 7027, according to findings published in Nature magazine.
Helium hydride — a combination of helium and hydrogen – was one of the first molecules to develop from atoms as for hundreds of thousands of years after the Big Bang, the universe was too hot and too full of radiation for atoms to bond together.
The study suggested that 100,000 years after the Big Bang, the universe cooled enough for helium and hydrogen to combine, forming the molecule known as helium hydride.
The same molecule was earlier produced and tested in a laboratory setting, however, this discovery marks the first time that the molecule has been detected in space, revealing the chemistry of the early universe, according to a statement from NASA.
