My eyes are not so good now, but way back when, I was a stargazer... One night while staring up at one of the brighter stars, it exploded in a orangey yellow white cloud. Then in an instant it was just gone from the sky. It was sooo far away there was no sound and looked like a small puff of smoke.
It made me sad because if that was really a sun "supernova" that possibly wiped out worlds and civilizations unknown. I still cry over something that could have happened billions of light years ago?
