Astronomers have spotted AT2025ulz, a rare dual explosion — a supernova and a kilonova — that may be the first-ever observed ...
A double blast of dying stars may be the first observed case of a long-hypothesized, never proven “superkilonova.” Although astronomers are still searching for concrete answers, a study published in ...
A massive star may have burst, leaving behind two dense, dead cores, which then collided and caused another explosion ...
New research explores how gravitational waves from black hole systems could help scientists study dark matter, using improved models and future detectors like LISA ...

2 neutron stars may have triggered the 1st known superkilonova
The cosmos has delivered a rare kind of fireworks display, and astronomers are racing to understand what it means. A strange double flash from a distant galaxy appears to show two neutron stars ...
A superkilonova candidate event, named AT2025ulz, was observed in 2025; LIGO and Virgo first spotted gravitational waves, ...
Astronomers may have discovered the first example of an explosive cosmic event called a "superkilonova," in the form of a gravitational wave signal detected on Aug. 18, 2025.
Astronomers may have discovered a never-before-seen cosmic explosion that effectively combines a supernova with a kilonova—the blast that results when two dead, dense stars collide. When massive stars ...
Neutron stars explained through stellar remnants and collapsed stars, revealing extreme density, gravity, magnetism, and ...
Astronomers report a strange cosmic blast that looked like a kilonova, then behaved like a supernova, hinting at a possible first “superkilonova” and leaving scientists debating how stars truly die.
New simulations of neutron star mergers reveal that the mixing and changing of tiny particles called neutrinos impacts how the merger unfolds, including the composition and structure of the merger ...
