and PASADENA, Calif., June 13, 2022 /PRNewswire/ -- New research from the Stratospheric Observatory for Infrared Astronomy (SOFIA) High-Resolution Airborne Wideband Camera Plus (HAWC+) provides evidence that the cosmic dust in the early universe was formed in supernovae.

  • Though theoretical models have previously shown that dust formation in supernovae could explain the presence of dust in the early universe, whether there would be evidence of sufficient amounts of dust forming remained an open question.
  • For one, the fact that polarized dust emission comes from an SNR implies that supernovae produce a large mass of dust and were important dust sources in the early universe.
  • The large amount of dust from the polarized regions of the SNR shows that supernovae are major dust producers in the early universe.

Universities Space Research Association's Jessica Sutter, the lead author of the study, investigatedthe various factors that can affect ionized carbon emission from a galaxy, including the galaxy's angle of inclination.

  • Universities Space Research Association's Jessica Sutter, the lead author of the study, investigatedthe various factors that can affect ionized carbon emission from a galaxy, including the galaxy's angle of inclination.
  • "One of the reasons more people haven't looked ationized carbon emission fromedge-on galaxies is because one can't do it from ground observations.
  • Because NGC 7331 is an inclined galaxy, the fraction of ionized carbon observed varied depending on which side of the galaxy was being observed.
  • With the help of SOFIA's unique ability tostudyionized carbon from within the Earth's stratosphere,we hope to expand this analysisby mapping ionized carbon emission from an additional set of galaxies", said Sutter.
