Clearest image ever of Betelgeuse’s companion | ESO News

Posted on: 28 Jul 2026, 8:00 am


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.

Astronomers Find a Sub-Neptune Orbiting Completely Backward Around a Red Dwarf
Posted on: 25 Sep 2026

In our own solar system, all eight planets orbit our Sun in a nice, orderly fashion. None are more than 7° or so out of alignment with the equator, and all of them rotate in the same direction as the Sun itself. But that’s not the case for all solar systems, and a new paper published in Astronomy & Astrophysics from a team of researchers led by Yann Carteret, a PhD student at the University of Geneva (UNIGE), describes the first time we’ve ever found an exoplanet orbiting the opposite direction of its red dwarf parent star - and it has major implications for our understanding of planet formation theory.
