Did you ping this out previously? The story looks familiar but I couldn’t find it by searching.

I admit that I have trouble grasping cosmic scales. Light years, parsecs, billions of years ... it’s hard to picture things at such scales.
But, having said that, if a star explodes, and we see the bright light for 6 months or so, that seems quite brief. Sure, with instruments we could detect fainter light over a longer time. I know that the nova itself didn’t start and stop over just a 6 month period. But, still, in terms of visible light seen by the naked eye, for a massive star to explode and just come and go in 6 months seems pretty counter-intuitive to me.

This is not new news, the Nova and the Crab Nebula ... I read about this 40 years ago, maybe more.
Disappointing our “scientific journals” have become tabloids, and/or agitprop like Scientific American.

Thanks for the corrections, gentlemen.
Irritates me to be wrong. Glad to get it right.

The only mistake I ever made was that one time when I paid extra for the pencils that came with erasers on the end of them.

Cosmic scales. Think of it this way. If our Sun were the size of a pea the nearest star, Proxima Centauri would be 125 miles away. The Sun is about 860,000 miles in diameter. The distances are just impossible to really comprehend.
A Supernova continues to put out a lot of energy for a long time. But the initial event is extremely cataclysmic. There are a lot of very informative astronomy videos on youtube. Search around sometime and prepare to be fascinated.

I'd be surprised if Erich von Daniken didn't use this image as proof of space aliens visiting. He would describe the thing in the sky as a rocket ship.

That’s supposed to be a comet - maybe Halley’s
