> Chandra’s study revealed the amounts of different elements produced by the explosion. The supernova has spat out 10,000 times the mass of the Earth in sulfur, 20,000 times Earth’s mass in silicon, 70,000 Earth masses of iron and a million Earth masses of oxygen.

Mind went supernova

Earlier quoted context omitted.

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.

A good premise for a sci-fi series: In the distant future, a large fleet of earth's best and brightest travels the stars while desperately trying to invent Earth's last ditch-effort to save its 12 billion inhabitants from a soon-to-be cataclysmic, near-earth supernovae: FTL travel. After decades of progress finally nears fruition, the fleet permanently loses contact with earth; humanity's home Solar System's remnants lost to the beautiful, nightmare... The fleet of 80,000 now works to save itself, the last of humanity.

Isn't that what every supernova does?

Some stars survive supernovae, and are known as zombie stars [1]. One believed example is SN2012Z [2] [1] https://en.wikipedia.org/wiki/Zombie_star [2] https://iopscience.iop.org/article/10.3847/1538-4357/ac3bbd/...

Here I was thinking "zombie star" was another term for ANY stellar remnant like a white dwarf or neutron star.

Wow it is absolutely fascinating and awe-inspiring. Anybody know what the blob (looks like wavy gold foil) in the bottom right of the picture is?

Should have read the description.

> There are also several light echoes visible in this image, most notably in the bottom right corner. This is where light from the star’s long-ago explosion has reached, and is warming distant dust, which is glowing as it cools down.
