Scientists Say That Uranus Appears to Have a Girlfriend

When checking out Uranus, scientists discovered something exciting: that the planet appears to have a long-term... well, call it a situationship. In a new, yet-to-be-peer-reviewed paper flagged by Universe Today, an international group of researchers detailed finding a so-called "Centaur" — a small, icy and rocky body that sits between Uranus and Neptune and is designated as a minor planet — that appears to have been keeping up with Uranus in a delicate cosmic dance for thousands or even millio

Embedding models transform each datapoint into a single-vector “embedding”, such that semantically similar datapoints are transformed into mathematically similar vectors. The embeddings are
