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.

Asymmetric space waves map pressure on Earth's magnetic shield
Posted on: 26 Oct 2026

The Earth’s magnetic field is responsible for shielding us from harmful space weather, including solar radiation from the Sun but also cosmic rays originating from outside our solar system. Cosmic rays can include deep space supernovas, so the magnetic field takes the majority of the brunt from solar radiation. Without our magnetic field, the solar wind would slowly strip away our atmosphere, making life on our small, blue world impossible to exist. But where is the magnetic field doing the heaviest lifting regarding how it filters out incoming space radiation?
