“A supernova is a dying star,” explains Girlyman memberDoris Muramatsu, who was diagnosed with leukemia in late 2010. The three founding members of Girlyman (Muramatsu,Nate Borofsky, andTylan Greenstein) had spent ten years playing and singing harmony together, from early days in tiny coffee...
When a giant star explodes like this, it’s called a supernova.To the naked eye, a supernova appears to be a bright new star, but it’s not a new star. It’s a dying star.However, the shock waves from a supernova excite nearby clouds of hydrogen gas, causing them to compress, ...

What is a supernova? A supernova is the explosion of a massive star. There are many different types of supernovae, but they can be broadly separated into two main types: thermonuclear runaway or core-collapse. This first type happens in binary star systems where at least one star is a...

limit. Stars of less than eight solar masses (M☉) or so are thought to end their lives as a long-lived stellar ember called a white dwarf star. Above the limit, dying stars can become neutron stars orblack holes. But before they do, these heavyweights will explode in a supernova. ...
Betelgeuse’s nucleus has been depleted as a result of nuclear fusion reactions, and the star has entered a new phase. Although in cosmic terms Betelgeuse is a young star, she has reached old age, inexorably heading for a violent and spectacular end. It will become a Type II supernova. ...
