Now the galaxy is full of gas and dust, which could hide a distant supernova optically, but the remnant would still produce detectable radio waves and X-rays. This lack is a significant puzzle." The discovery of the young remnant does not immediately provide an answer to the puzzle, but scientists say it will be a "goldmine" to study, since it is still so recent and energetic. They say it is an important finding for understanding the life cycles of stars in the Milky Way galaxy. Bob Kirshner, of Harvard University, explains why supernovae are important for all of us. "The supernovae make the chemical elements through real alchemy, transforming one element, the light elements into the heavy ones. So the calcium that is in your bones and the iron that is in your blood probably came from supernovae that exploded before the sun formed. So, we are all stardust, and it seems reasonable for us to want to know how these elements get formed when stars explode."
