Supernova Explosions

Astronomers may have detected the first 'whispers' of ghost particles, which are believed to be created by supernova explosions. The discovery could provide insights into high-energy astrophysical processes.

Scientists achieved a breakthrough by recreating a rare cosmic reaction, directly measuring the creation of selenium-74 using a rare isotope beam. This advances understanding of proton-rich element formation in supernova explosions, though gaps in current theories remain.
