just watched this crazy video from NASA and I'm still trying to wrap my head around it 25 years of footage from a supernova remnant 
... it's like something out of science fiction https://www.nasa.gov/feature/goddard/nasa-c captures stunning X-ray images of the remnant's expanding ring structure 
I mean, think about it - we're talking about an explosion that happened 17,000 light-years ago and yet we can still see the effects today
... it's mind-blowing stuff . And to know that this research is helping us understand our cosmic history and how supernovae impact surrounding environments is just amazing
