"While a supernova is the explosive death of a massive star, a nova refers to the sudden, brief explosion from a collapsed star known as a white dwarf." - "Once the nova peaks in brightness, it will be as if a new star has appeared one that’s visible for a few days without any equipment and a little over a week with binoculars before it dims and disappears from sight for another 80 years or so." https://www.cnn.com/2024/03/19/world/t-coronae-borealis-nova-new-star-scn/index.html
Nothing bad here, another nova in the sky to look at. The point of like a natural selection over all the time in galaxy everything had time to crash or burn to be inline with a working galaxy!
Or the old Gnostic saying, If you want to know about the ending, it's where the beginning is.
