• Resumen

  • The article discusses the death of stars and research that suggests dying stars are more explosive than previously thought. A personal narrative is presented which explores the author experience of using the telescopes at the W. M. Keck Observatory on Mauna Kea in Hawaii to search for supernovae progenitors. Topics include the challenges of locating a star that became a supernovae prior to its explosion from archival images taken by the Hubble Space Telescope, thermonuclear explosions of some supernovae that may have been triggered by the creation of matter and antimatter particles, and speculation that the first generation of stars in the universe, which created materials that formed planets, may have exploded through a similar mechanism.
