Our planet is bombarded with tons of extraterrestrial dust every year. While much of the dust comes from asteroids, some of these particles may have come from supernovas - ancient stars that exploded nearly 20 million years ago! But finding this dust on Earth is tricky, and determining that the dust came from an exploding star is even tougher. This week Charlie takes on a new study from some “stellar” researchers who were up to the challenge. Thanks to Ben from Australia for the paper recommendation this week!
