Astronomers have found a start that has gone supernova multiple times. https://www.extremetech.com/extreme/258842-one-supernova-isnt-enough-researchers-find-star-thats-exploded-six-times
I know that this is science and not tech, but I found it fascinating and felt compelled to share.
What I really appreciated was the last sentence: " In short, we don’t have a great explanation for this star’s behavior, yet–and it’s an excellent example of how, even after millennia of watching the sky, we’re still learning how much we don’t know."
I like it when humility is expressed, especially in science.
