Supernovae: Dust Suppliers and Galaxy Builders, Webb Observations Reveal

Astronomers have long assumed that supernovae are the main source of interstellar dust, but direct evidence has been lacking. However, observations from the James Webb Space Telescope (JWST) have now confirmed that supernovae do indeed seed early galaxies with dust. The team observed high quantities of dust in the remnants of two supernovae, demonstrating how quickly supernovae can contribute large amounts of dust to interstellar space. This discovery will help advance our understanding of how early galaxies evolved and the variations in dust composition caused by different supernova origins.
