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.
According to scientists, red supergiant stars should produce more supernovas. But astronomers just aren’t spotting them. Here's how they plan to crack the case.
Astronomers have captured a first-of-its-kind image of a massive dying star. Just 26 hours after the supernova SN 2024ggi was first detected in April 2024, the European Southern Observatory (ESO) ...

For centuries, scientists have studied supernovae mostly after the damage was already done, looking at remnants long after ...
The brightest cosmic object of its kind ever detected may have helped astronomers solve the mystery of powerful, bright blue cosmic explosions. At the heart of the discovery is a signal from a ...
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 ...
"With ALMA, we can now see the atmosphere of a dying star with a level of clarity in a similar way to what we do for the sun." When you purchase through links on our site, we may earn an affiliate ...
