The Invisible Force Behind Betelgeuse's Strange Behavior

Dive into the mystery of Betelgeuse's intriguing companion star! Scientists have found evidence of a sun-sized "Beetle Buddy" orbiting the red supergiant, helping explain its puzzling 2,170-day brightness cycle. Learn how this companion acts as a cosmic snowplow, clearing paths through Betelgeuse's dust clouds and potentially influencing its eventual supernova.

In this episode, we explore:

  • How astronomers detected the hidden companion
  • What this means for Betelgeuse's future supernova
  • Why this companion orbits at a surprisingly close distance
  • The role of dust and debris is Betelgeuse's brightness changes
  • How the Nancy Grace Roman Space Telescope could revolutionize our understanding with its powerful coronagraph technology.


Coming soon: The Nancy Grace Roman Space Telescope may give us our first direct look at Betelgeuse's mysterious companion through advanced spectroscopy and imaging!


💫 Whether you're a seasoned astronomer or just curious about the cosmos, join us for this fascinating journey into one of astronomy's most exciting recent developments!
