Astronomy Cast Ep. 786: Wolf-Rayet Stars By Fraser Cain & Dr. Pamela Gay Streamed live on Mar 9, 2026. You think the Sun is a terrifying ball of fire and fury? Wait until you learn about today's topic: Wolf-Rayet stars! These are massive, dying stars hurling their outer layers out into space before detonating as supernovae. Big stars live brief lives, and Wolf-Rayet stars are the punctuation mark we see before things go supernova.
