00:00Stars don't just shine forever, they die.
00:04And when they do, some don't fade quietly, they explode.
00:11When a massive star runs out of fuel, its core collapses in on itself, in less than a second.
00:18Then, everything rebounds outward.
00:21A supernova, releasing more energy than our sun will in its entire lifetime.
00:27For a moment, one dying star can outshine an entire galaxy.
