A new study led by Ryan Lau of Cornell University has found new evidence to support the hypothesis that much of the dust observed in galaxies, including our own Milky Way, was generated by supernovae. According to a Cornell statement, Lau and colleagues obtained the first ever direct observations of dust at the Milky Way’s heart.
The observations were made using the Fain Object Infrared Camera Telescope installed on the Stratospheric Observatory for Infrared Astronomy (SOFIA). This retrofitted Boeing 747 is a collaboration among NASA, the German Aerospace Center, and the Universities Space Research Association.
