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.

Betelgeuse Is Disturbed By Its Companion Star
Posted on: 28 Oct 2026

Betelgeuse has a close-orbiting companion that disturbs the red supergiant into an egg-like shape. New observations show how the two stars interact and how this could help explain the varying brightness of Betelgeuse.

Ancient Comets Carried Organic Compounds, But They Didn't Survive Crashing Into Earth
Posted on: 28 Oct 2026

Perhaps the biggest mystery we face is life on Earth started. One hypothesis says that comets, which are known to carry important chemicals in abiogenesis, delivered these compounds to Earth, leading to the appearance of life. But new research concludes that that is highly unlikely.
