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.

Informed by science from the Smithsonian Astrophysical Observatory and astronomers worldwide, this “documentary that you can walk through” visualizes the cosmos in a 3-D introduction to the universe ...

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 team of nuclear physicists has pulled off something that, until recently, existed only in theoretical models and the violent surfaces of collapsed stars: they recreated a thermonuclear reaction ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. If predictions come true, June 25 could see a dim star in ...

For centuries, scientists have studied supernovae mostly after the damage was already done, looking at remnants long after the original explosion disappeared. But in April 2024, the ATLAS survey ...

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 ...

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 ...

Scientists still don’t know where ghostly particles called neutrinos originate. A distant galaxy could be a potential source.
