Kuchner, Marc J., 1972- Cosmic collisions

"It's time for the next round of outer-space, crash-and-smash fun, and this matchup is colossal! Two red supergiants are facing each other, ready for a scuffle. Each cranks out 100,000 times as much power as the Sun. (Don't get too close or you'll roast like a weenie in a campfire.) These mighty stars are equally matched, so either could come out on top-but hold on! One of the contenders has just exploded! And it's left behind a neutron star with supernova energy. Now who will be left standing after this interstellar smack down?" --
