<\/div>According to new research, half the calcium in our universe came from “calcium-rich supernova.” That means the stuff our teeth and bones is made from is, essentially, the remains of dead stars that blew up a long, long time ago.<\/p>
“These events are so few in number that we have never known what produced calcium-rich supernova,” said Wynn Jacobson-Galan, Northwestern graduate student and lead author of the new study<\/a> published in The Astrophysical Journal <\/em>this week, in a statement<\/a>.<\/p> “By observing what this star did in its final month before it reached its critical, tumultuous end, we peered into a place previously unexplored, opening new avenues of study within transient science,” Jacobson-Galan added.<\/p> An extremely bright event some 55 million light years from Earth grabbed the attention of the international astronomy community in April 2019. “Every single country with a prominent telescope turned to look at this object,” Jacobson-Galan recalled.<\/p> Astronomers were so quick that many observed the supernova just ten hours after the explosion. “The explosion is trying to cool down,” Raffaella Margutti from Northwestern University and a senior author of the study, explained in the statement. “It wants to give away its energy, and calcium emission is an efficient way to do that.”<\/p> As it turns out the explosion spewed out an immense amount of calcium. “It wasn’t just calcium rich,” Margutti said. “It was the richest of the rich.”<\/p> They caught the event just in time to conclude that it was the most calcium to have ever been observed to be emitted from just a single event.<\/p> “The luminosity tells us how much material the star shed and how close that material was to the star,” Jacobson-Galan explained. “In this case, the star lost a very small amount of material right before it exploded. That material was still nearby.”<\/p> READ MORE: <\/strong>Exploding stars created the calcium in our bones and teeth, study says<\/a> [CNN<\/em>]<\/p> More on supernovae: <\/strong> This Star Appears to Have Survived a Supernova<\/a><\/em><\/p> The post Your Bones Are Made Out of Exploded Stars, Scientists Say<\/a> appeared first on Futurism<\/a>.<\/p> Read this article: According to new research, half the calcium in our universe came from \u201ccalcium-rich supernova.\u201d That means the stuff our teeth and bones is made from is, essentially, the remains of dead stars that blew up a long, long time ago. \u201cThese events are so few in number that we have never known what produced calcium-rich supernova,\u201d said Wynn Jacobson-Galan, Northwestern graduate student and lead author of the new study published in The Astrophysical Journal this week, in a statement .
