flag Scientists find new supernova type, SN2021yfj, revealing rare insights into star evolution.

flag Astronomers have discovered a new supernova type, named SN2021yfj or Type 1en, offering a rare view into a star's inner layers. flag Found 2 billion light-years away, this supernova shows the star had lost its outer layers, revealing heavier elements like silicon before exploding. flag This discovery challenges current theories of stellar evolution and suggests that massive stars might lose significant material before exploding, a phenomenon that could be rare but important for understanding star evolution. flag Future telescopes may help find more such events.
