About this episode
Astronomers have finally obtained firm evidence that Betelgeuse, a famous star in the Orion constellation, is not alone. Using ESO’s Very Large Telescope (VLT) they have obtained the clearest image ever of what likely is Betelgeuse B, a star orbiting Betelgeuse and which could explain some of its brightness variations. This video summarises the discovery.
