The Probable Direct-Imaging Detection of the Stellar Companion to Betelgeuse: [oops, the paper will only go on ArXiv tonight and appear in ApJL on 24 July] -> Gemini North Discovers Long-Predicted Stellar Companion of Betelgeuse: #Betelgeuse, solving millennia-old mystery. The picture here is from the actual paper which has been sent to me ... compare it to the spiced-up version in the press release! The authors themselves say it's only a 1.5 sigma detection but because it fits the expectations for a 'Betel buddy' so well, they believe it. See skyweek.wordpress.com/2025/07/ for more discussion!
