One of the largest questions to date has been what building materials were present at the formation of our Milky Way galaxy? Astronomers have long theorized that the building material may have come from the death of supermassive stars, however, the galaxy-building dust is thought to burn up in a supernova like that. But now researchers are saying that may not be the case at all. In a new study published this week in the journal Science Express, researchers with Cornell University have made the first direct discovery of dust used to build the cosmos at the center of the Milky Way, and they believe it may have resulted from an ancient supernova.
