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.

Hera Probe Sees Asteroid Pair Separately for First Time
Posted on: 30 Oct 2026

Planetary defense is a growing concern among the scientific community, as efforts have been made to design and implement missions meant to deflect incoming threats to the Earth well in advance. In 2022, NASA intentionally collided the Double Asteroid Redirection test (DART) planetary defense spacecraft into the smaller asteroid of the binary asteroid, Didymos and Dimorphos, with the latter being the smaller one. While the goal was to ascertain if deflecting an asteroid is feasible, how did this influence the geological characteristics of Dimorphos, and what can it teach us about planetary defense missions?

What Could Split a Black Hole in Two?
Posted on: 30 Oct 2026

We all know that black holes can collide. It has happened since black holes began to form, early in cosmic time. The result is always a clash that gives off gravitational waves and a giant bang. Since black holes have such strong gravity, it's almost impossible to imagine a way that any force could break one apart. Yet, that's the task that a group of scientists in Europe set for themselves.
