Exploding stars are rare but emit torrents of radiation—one close enough to Earth could threaten life on the planet

Stars like the sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the sun shining steadily for about ...
