EVANSTON, Ill. - The famous astronomer Carl Sagan once said that “we are made of star stuff.”A new study suggests that Sagan might have been right.
Most of the calcium in the universe likely came from exploding stars, according to an Aug. 5 press release from Northwestern University.Stellar explosions, known as “calcium-rich supernovae,” are so rare that astrophysicists had difficulty tracking and studying them.
The nature of the supernovae and how they created calcium has remained relatively unknown.Now, researchers may have discovered the workings behind supernovae and how they create calcium.
