Astronomers studying the Jellyfish Nebula—an extensively observed supernova remnant—report evidence that it contains explosions from two stars. Multiple outlets describe the finding as exceptionally rare: what appears to be a binary star system in which both members undergo supernova. Researchers suggest that the progenitor system includes a pair of “sibling” stars whose explosions occurred at different times, rather than a single supernova event. One source indicates the earlier supernova may have happened roughly 100,000 years before the other, implying a staggered timeline within the same remnant region. The overall interpretation is that the nebula may be hiding a related supernova remnant from the companion star. If confirmed, the discovery would offer a new perspective on how binary massive stars evolve and how their end-of-life explosions shape surrounding gas and dust. The reports emphasize that this is the first time astronomers have identified such a double supernova scenario, pairing both stars’ endpoints within a single, well-studied galactic remnant.

- Astronomers are investigating the Jellyfish Nebula, a well-studied supernova remnant.
- Evidence suggests two stars in a binary system both explode as supernovae.
- Researchers propose the two supernova events occur at different times, with one estimate placing the earlier explosion about 100,000 years before the other.
- The finding is described as potentially the first known example of a binary system where both stars produce supernova remnants.
- The results aim to provide a new view of how massive binary stars end their lives.
The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, according to international researchers, who say that this may be the first known discovery of a binary star system in which both stars have gone supernova.
