New Cosmic Explosion: Superkilonova Discovered in AT2025ulz

12/18/2025

Summary

Story summary

AT2025ulz may represent a new cosmic explosion type, a 'superkilonova,' arising from a supernova that forms two neutron stars which collide to make a kilonova.
Initial observations showed AT2025ulz glowing red like GW170817, but it later shifted to blue, indicating supernova characteristics.
Researchers theorize the unusual behavior stems from one neutron star being less massive than the Sun, suggesting a complex interaction between processes requiring further observations.
