I have a busy day in front of me here in Not-Barcelona so I thought I’d do a quick post sharing a video about the Euclid Early Release Observations (EROs) that came out last week. The press materials accompanying the release of the EROs and the science paper relating to this work, mention “freely floating planets”, but that doesn’t make sense in terms of the modern definition of a planet so here they are described as sub-stellar objects. The paper describing this work can be found on the arXiv here.
