NASA Scientist Finds Predicted Companion Star to Betelgeuse
A century-old hypothesis that Betelgeuse, the 10th brightest star in our night sky, is orbited by a very close companion star was proved true by a team of astrophysicists led by a scientist at NASA’s Ames Research Center in California’s Silicon Valley. The research published in The Astrophysical Journal Letters in the paper “Probable Direct Imaging Discovery of the Stellar…
