Neutron stars are among the most mysterious objects in the universe. Formed when massive stars collapse after exploding as ...

New studies reveal how metallicity and stellar evolution determine whether massive stars expand into red supergiants prior to Type II supernova explosions.

When most people think of a supernova, they're thinking of a Type II core-collapse supernova. These are massive stars that have reached the end of their time on the main sequence. They've used up ...

An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.

DOE Vera C. Rubin Observatory has launched a real-time alert system, capable of issuing up to 800,000 alerts per night, to track asteroids and exploding stars.

The Rubin Observatory’s real-time alert system can detect millions of cosmic events per night, from asteroids to supernovae, ...

The new Vera C. Rubin Observatory now automatically sends out alerts when something changes in the night sky. In the first night, there were 800,000.

NASA has detected a precursor or progenitor to a supernova for the first time – and it's all thanks to old photos.

The NSF-DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation and the U.S. Department of Energy's Office of Science ...

Forty million years ago, a star in a nearby galaxy exploded, spewing material across space and generating a brilliant beacon of light. That light traveled across the cosmos, reaching Earth June 29, ...

A supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole with a "dark charge." If true, this theory could lead to a definitive catalog ...

The expolision of a black hole could explain the origins of a mysterious high-energy neutrino detected in 2023, as well as shedding more light on the mystery of dark matter in the process. In 2023, a ...
