The large barred spiral galaxy appears close to a smaller galaxy to the left, but they’re actually about 45 million light-years apart 👉 https://www.esa.int/ESA_Multimedia/Images/2025/12/Euclid_s_galaxy_garland

Au revoir Yannick!
Dear colleagues and friends,
It is with the greatest sadness that we announce the passing of Yannick Mellier, which occurred during the night between Friday and Saturday. His death leaves a huge void within the consortium and our community.

We followed up #ESAEuclid's near-infrared image of the Dark Cloud LDN 1641 with a comparison to the NIR 2MASS survey, and to a bespoke ground-based image in visible light.

Those were beautiful #aurorae in the past days. A solar storm brought a lot of protons to Earth. Not only to Earth but also to #ESAEuclid – but does #Euclid notice? Oh yes.
