Traces of Fe-60 iron isotopes from supernovae within the last ten million years have been discovered on Earth in marine deposits such as those drilled in cores in the east Indian Ocean. The deep-sea ...

What can imaging supernovae (plural for supernova) explosions teach astronomers about their behavior and physical characteristics? This is what a recent study published in Nature Astronomy hopes to ...

Stars often die with a final burst of beauty. For the first time, astronomers have captured visual proof that a star can explode not once, but twice before fading forever. Using the European Southern ...

You’d think that supernovae – the death throes of massive stars and among the brightest, most powerful explosions in the universe – would be hard to miss. Yet the number of these blasts observed in ...
