The light did not fade the way it was supposed to. After blazing into view about a billion light-years from Earth, the supernova known as SN 2024afav settled into something stranger.

Astronomers have identified the birth of a magnetar, a hyper-magnetized neutron star, by detecting a subtle warping of ...

In December 2024, astronomers witnessed the rare eruption of a superluminous supernova about a billion light-years away from Earth. Even among powerful supernova explosions, those termed ...

Some of the most extreme explosions in the universe are Type I superluminous supernovae. “They are one of the brightest explosions in the Universe,” says Joseph Farah, an astrophysicist at the ...

Add Yahoo as a preferred source to see more of our stories on Google. On the outskirts of the Milky Way, one of the rarest kinds of stars in the galaxy has just become even more mysterious than it was ...

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

Astronomers at NASA and ESA have discovered the youngest pulsar known. This celestial child is a mere 240 years old, and its birth would have been visible on Earth at the time as a supernova. In ...

Gamma rays are a broad category of high-energy photons, including everything with more energy than an X-ray. While they are often created by processes like radioactive decay, few astronomical events ...

For the first time, astronomers have definitively spotted a flaring magnetar in another galaxy. These ultra-magnetic stellar corpses were thought to be responsible for some of the highest-energy ...
