To date, there’s only sufficiently robust evidence for the existence of two classes of supernovae—that is, star explosions. But there have been plenty of signs that there are likely other types in the ...

The exploding stars known as Type Ia supernovae serve an important role in measuring the universe and were used to discover the existence of dark energy. They are bright enough to see across large ...

It’s easy to forget that stars, just like us, have lifetimes. They’re born, they live, and eventually, they die. And for some stars, their death is dramatic, producing an explosion so powerful it can ...
