Get to know the people working in the UK to make the @vrubinobs.bsky.social LSST happen. We caught up with @cfrohmaier.bsky.social to find out more about his work with @4most-eu.bsky.social TiDES and what he's looking forward to most about the Rubin survey 🔭 www.lsst.ac.uk/news/2025-09...

Between busy nights, our systems verification crew have had some time to explore Cerro Paranal! It is from this mountain that 4MOST will operate, observing 2400 objects at a time ✨🔭

This is a top-down image of the front of a new instrument for ESO’s telescopes. At its outer edges is a ring of metal, within which sits a hexagonal structure made of thousands of fibres that are standing upright. From this angle, each one looks like a single point, and some of the fibres have been moved closer together so that they form a pattern within the hexagon. For this image, the pattern is the shape of a large number four.
