Some stars explode as they die. We look at their life cycle
This summer, scientists have their eyes and telescopes trained on the small constellation system T Coronae Borealis. They think it will explode as part of a periodic nova — a once-in-a-lifetime event according to NASA scientists. And so, with the help of astrophysicist Sarafina El-Badry Nance, we continue our journey farther and deeper into spacetime with a look at the stars: How they're born and how they die. Sarafina has always been drawn to one particular star: Betelgeuse, a red supergiant in the shoulder of the constellation Orion that is nearing the end of its life.
