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.

One of the largest known stars in the cosmos is poised for catastrophe. After witnessing the massive object undergo a dramatic transformation, a team of astronomers say the star is on the verge of ...

For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed ...

A University of Virginia doctoral student and a team of astronomers have, for the first time, captured radio waves from a rare class of exploding star, giving them an unprecedented look into the final ...

Artist’s conception of a magnetar surrounded by an accretion disk that is wobbling, or precessing, because of the effects of general relativity. Some models of magnetars suggest that high-speed jets ...

A massive star 2.5 million light-years away simply vanished — and astronomers now know why. Instead of exploding in a supernova, it quietly collapsed into a black hole, shedding its outer layers in a ...

In 2014, a NASA telescope observed as the infrared light emitted by a massive star in the Andromeda galaxy gradually grew brighter. The star glowed more intensely with infrared light for around three ...

Scientists have seen something spectacular unfolding in Andromeda, our neighboring spiral galaxy, located some 2.5 million light-years away from Earth. The spectacular part is actually what they ...
