Astronomers identify rare supernova candidate, ancient cluster gap (opens in new tab)

Astronomers studying SN 2023vbw say the blast may be a pair-instability supernova, a rare type of stellar explosion that can destroy a massive star without leaving a neutron star or black hole remnant. The object was first detected in 2023 in a dwarf galaxy about 1.3 billion light-years away, and the study cited by Futurism was awaiting peer review as of June 7, 2026.
