Big Dipper, Small dipper and Orion's belt - These are just some of the constellation of stars in the Milky Way galaxy that we commonly know about. But according to researchers, recently, astronomers have discovered the secrets of the powerful explosion that happened billions of years ago known as Hypernovas. Could they have ruled the Milky Way during its younger years?
As reported by CBS News, the most aged stars in the entire universe lack in "metals" or Helium. As these stars die of bursting, they are called Supernovas; spreading these "metals" to the galaxy. And as time passes by, new born stars become richer in helium than the previous ones.
13.6 billion Years ago, the first stars were born. And according to previous research, this might just have started the cosmic dawn. Astronomers haven't actually found out what the first star was yet, however, they believe that those stars that lack in "metal" content could possibly be the ancestors of the first star to have ever been seen in the Milky Way or around its outer regions.
