The brightest star in Orion was hiding a ‘sidekick.’ Imagine a lighthouse with a dim little light circling nearby. The Gemini North telescope has caught that light for the first time—Betelgeuse’s stellar companion, 250 times fainter. So the supernova blast is postponed, and we can keep watching the pair’s life unfold.
🎯 Unofficial names for the companion are Betelbuddy or Siwarha. Its full orbit around Betelgeuse takes just a few years—by cosmic standards, a very brisk dance.
