Astronomers have recently spotted a new kind of supernova, SN 2019odp, that is a surprisingly oxygen-rich and massive star. Found in the galaxy UGC 12882, this supernova holds a remarkable amount of oxygen, the largest amount ever found in a star of its kind. This finding has surprised and excited astronomers, as it helps to shed light on the processes behind stellar explosions. SN 2019odp is a Type IIb supernova, a special kind of stellar explosion that occurs when a star runs out of nuclear fuel. This type of supernova is known for being very bright and having a characteristic spectrum. However, SN 2019odp is special in that it is not only very bright, but also extremely oxygen-rich. This is a rare occurrence, as Type IIb supernovae are usually not oxygen-rich.
