Episode Description from the Publisher

What is the largest star, and where can it be found? For a few years now, it has been known as Stephenson 2-18, often claimed to boast a diameter more than 2,100 times our sun’s. But is this estimate really reliable? And if not, then what other giant stars may be lurking out there? These are the questions we will be aiming to answer as we wind back the clock in search of the real “largest star”. MUSIC: - Holographic Rain - CO.AG Music (https://www.youtube.com/watch?v=37aEn7yuChQ)- Strange Visions (Giuseppe Rizzo)- Endless Mist (Enzo Orefice)- Dystopia - Instrumental (Efliz) - Nights of Darkness 01 - CO.AG Music (https://www.youtube.com/watch?v=FwC9HZv7Zw0)- Static Balance (Enzo Orefice)- Agnus Dei (Michele Nobler)- Light the Way (Enzo Orefice)Artists: - Enzo Orefice: https://www.music-bay.net/artists/enzo-orefice/- CO.AG’s music channel: https://www.youtube.com/@co.agmusicCHAPTERS: 00:00: What is the Largest Star? 01:48: It’s Not Stephenson 2-18 05:20: Modern-day Contenders11:30: Primordial Stars15:47: Quasi-Stars 18:11: MoM BH*-1: Webb’s New Black Hole Star 22:28: A Source of Galactic Engines?26:20: The REAL “Largest Star”
