It's kind of fun to think that at any moment something might pop and our entire solar system would disappear in a blink of an eye.

Our sun isn’t massive enough to ever go supernova.

Supernova are powerful enough that even a star in a different solar system going nova can kill you, if it's a "nearby" system. But I believe there aren't any stars close enough that would go supernova any time soon.

It wouldn't wipe out the solar system, but might have harmful impacts on our biosphere.

Was wondering what the width of the image we're seeing is, so I did some quick googling:

> The expanding cloud of material left over from the supernova now appears approximately 10 light-years (3 pc) across from Earth's perspective

Isn't that what every supernova does?

“Shattered” seems like an odd way of describing it but at some level… sure.

Would love for an astrophysicist to pine in. But my understanding is supernovae are usually balanced enough to squeeze their stars' cores. This appears to have been unbalanced such that the core was "broken" instead of uniformly compressed.

It's always the one you don't expect that gets you.
