These cosmic phenomena, called <a href=\"https:\/\/scitechdaily.com\/astronomy-astrophysics-101-supernova\/\">supernovae<\/a>, spread light, elements, energy, and radiation in space and send galactic shock waves that could compress gas clouds and generate new stars. In other words, supernovae shape our universe. Among these, hydrogen-poor supernovae from exploding massive stars have long puzzled astrophysicists. The reason: scientists have not been able to put their finger on their precursor stars.
