Researchers say the "powerful engine" behind superluminous exploding stars had been hidden for years — until a "chirp" from the cosmos helped confirm their link.

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 ...

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 ...

In December 2024, the ATLAS astronomical survey detected a distant flash of light. It was a supernova, the explosive death of a massive star, located far, far away, roughly a billion light-years away.

You're not prepared for its size. The post Evidence Grows That One of the Largest Known Stars Is Poised to Explode in a ...

Asrtronomers managed to pinpoint which star in the NGC 1637 galaxy turned into a supernova 40 million years ago, they used the Webb telescope.

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, ...

Betelgeuse is one of the closest stars to Earth, at a distance of only 650 light-years away. This makes Betelgeuse a fan-favorite with professional and amateur astronomers alike. Betelgeuse is a red ...

Astronomers have discovered the first radio signals from a unique category of dying stars, called Type Ibn supernovae, and these signals offer new insights into how massive stars meet their demise.
