Astronomers Propose New Method for Detecting Neutron Star Collisions

Astronomers have identified a potential new technique to detect neutron star collisions by observing unusually prolonged bright X-ray emissions, exemplified by an event in July 2025. This discovery suggests that some previously unexplained fast X-ray transients could be hidden neutron-star mergers, providing valuable new insights into these powerful cosmic phenomena and improving our ability to identify them.
