Meteoritic stardust unlocks timing of supernova dust formation

(Carnegie Institution for Science) Dust is everywhere — not just in your attic or under your bed, but also in outer space. To astronomers, dust can be a tool to study the history of our universe, galaxy, and Solar System. For example, observations indicate that type II supernovae — explosions of stars more than ten times as massive as the Sun — produce copious amounts of dust, but how and when they do so is not well understood.
